How do I find the catalogID for songs in a apple music playlist? (MusicKit & Apple Music API)
Hello, How do I find the apple music catalogID for songs in a apple music playlist? Im building an iOS app that uses MusicKit/Apple Music API. For this example, you can assume that my iOS app simply allows users to upload their apple music playlists. And when users open a specific playlist, I want to find the catalogID for each song. Currently all the songs are returning song IDs in this format “i.PkdJvPXI2AJgm8”. I believe these are libraryIDs, not catalogIDs. I’d like to find a front end solution using MusicKit. But perhaps a back end solution using the Apple Music Rest API is required. Any recommendations would be appreciated!

Apple Music API - relationships and views are broken
I am testing the Music API and I am hitting walls every single moment when I try to do something that is DOCUMENTED but doesn't work/exists. Documentation says, /v1/catalog/us/artists/{ID}/view/{view}/ NEVER returns 404, while I am getting 404 for even content I know it's available on Apple Music. e.g /v1/catalog/us/artists/1487603897/view/appears-on-albums/ results 404 while they are appearing on an album FRIGID TORTURE of Nosphere artist. So when I request for appears-on or featured albums it shoud appear as a result, but I get 404. It's here so it should appear: https://music.apple.com/us/album/frigid-silence/1791001624?i=1791001626 I found NO WAY to get that album for this artist using the API, which is very frustrating and annoying. Similarly if I try this: /v1/catalog/us/artists/{ID}?views=>appears-on-albums it will result an EMPTY array for the data property Also the documentation is unclear about the several limitation max values, many parameters (e.g. include parameters are unknown ) we can't tell what value can we use. Is Apple Music Api unreliable or I just don't understand something?! I don't even understand why I have to do 4 different requests to get an artists all albums (full, single, featured, appears-on)... this should be MUCH more easier to do it one single request (with pagination). We are working on a long-term major investment in music startup and trying to move from Spotify API (due to recent changes and limitations) and finding a better alternative. Based on the docs Apple Music API seemed the most promising one, but now we are testing it we are very disappointed so far. So should we trust in this or should we forget about Apple Music API?

Can I Fade Out Track Volume Before End Using ApplicationMusicPlayer?
I’m building a music app using Apple Music streaming via ApplicationMusicPlayer. My goal is to decrease the volume of the current song during the last 10 seconds, and when the next track begins, restore the volume to its normal level. I know that ApplicationMusicPlayer doesn’t expose a volume API, and I want to avoid triggering the system volume HUD. ✅ Using Apple Music streaming (not local files) ❓ Is it possible to implement per-track fade-out/fade-in logic with ApplicationMusicPlayer? Appreciate any clarification or official guidance!

Unable to play audio via MusicKit
Hey folks, I'm running into an odd issue suddenly with an app that had a working MusicKit integration before. I'm using ApplicationMusicPlayer to play Apple Music albums and songs. I'm testing on a physical device, signed in to Apple ID, and with a valid subscription. Apple Music via the first-party app works entirely fine on this device. Attempting to play back any content at all gives the log: <ICUserIdentityStoreACAccountBackend: 0x1070bf3e0> Failed to initialize primary apple account, error=Error Domain=ICError Code=-7013 "Client is not entitled to access account store" UserInfo={NSDebugDescription=Client is not entitled to access account store} [ICUserIdentityStore] - initializing account histories with activeAccountDSID = nil, activeLockerAccountDSID = nil, timestamp = 14605951908 [ICUserIdentityStore] Failed to fetch local store account with error: Error Domain=ICError Code=-7013 "Client is not entitled to access account store" UserInfo={NSDebugDescription=Client is not entitled to access account store}. The album artwork, track names, etc, all appear in the control center playback controls, but the music doesn't play. Trying to trigger playback with control center just results in it skipping to the next track, which doesn't play either. This exact code used to work. I have the MusicKit service selected in Apple Connect. Since this isn't entitlement-based, I'm not sure how else to check that I'm set up correctly. I've tried deleting/reinstalling the app, restarting the device, cleaning/rebuilding, and deleting DerivedData, to no avail. Any help? Running Xcode 16.4 (16F6), testing on iOS 18.5 (22F76)

All boys wanna access Media Library (sung to All Gurls Wanna Have Fun)
Howdy. I'm trying to access media from a users song library and receive: <ICUserIdentityStoreACAccountBackend: 0x148f8af30> Failed to initialize active account, error=Error Domain=ICError Code=-7013 "Client is not entitled to access account store" UserInfo={NSDebugDescription=Client is not entitled to access account store} I'm told I need to add a Media Library Access Capability. Nothing like this shows up in Xcode under Signing & Capabilities > +Capabilities. Also I can't find anything like this in my account in dev.apple.com. How do I enable myself and a test user using another iPhone device to access my music and their music respectively? Thanks!

MusicKit developer token issue
I'm reaching out regarding a recurring issue I'm experiencing with MusicKit developer tokens. I'm using a valid .p8 private key to sign JWTs for Apple MusicKit integration. Each token I generate includes the appropriate claims (iss, iat, exp) and is signed with the ES256 algorithm, with an expiration date set approximately 6 months ahead. Everything works as expected immediately after generating the token. However, after a few days, the same JWT (still well within its expiration period) suddenly begins returning invalid/unauthorized responses when used in Postman and other API clients. Importantly: I did not delete or revoke the .p8 key during this time. I verified the JWT contains valid claims and a proper structure. The issue consistently resolves only when I create a new .p8 file and regenerate a fresh JWT with it—after which the cycle repeats. This issue occurs even when the environment and app identifiers remain unchanged. I would greatly appreciate it if you could help me understand: Why these tokens become invalid after a few days, despite having a long exp value and an unchanged key. Whether there's any automatic revocation or timeout policy on .p8 keys that could explain this behavior. If there's a better way to maintain long-lived developer tokens without requiring new .p8 key generation every few days. Thank you for your help and clarification on this issue. Best regards, Liad Altif

Is there a way to limit the MusicKit JWT tokens to just the Apple Music API using scopes?
Hi, I'm generating MusicKit JWT tokens on my backend side and using it on the client side to query the Apple Music API. One concern I have is accidentally over issuing the scope of this JWT, resulting in accidental access more services than intended like DeviceCheck or APNS. Other than using separate keys for MusicKit and other services, is there a way to limit the generated JWT to only the Apple Music API (https://api.music.apple.com/v1/*) using the JWT payload scope?

MusicKit playbackTime Accuracy
Hello, Has anyone else experienced variations in the accuracy of the playbackTime value? After a few seconds of playback, the reported time adjusts by a fraction of a second, making it difficult to calculate the actual playbackTime of the audio. This can be recreated by playing a song in MusicKit, recording the start time of the audio, playing for at least 10-20 seconds, and then comparing the playbackTime value to one calculated using the start time of the audio. In my experience this jump occurs after about 10 seconds of playback. Any help would be appreciated. Thanks!

Editing a Library Playlist (MusicKit: iOS 16 beta)
I've just begun to dip my toes into the iOS16 waters. One of the first things that I've attempted is to edit a library playlist using: try await MusicLibrary.shared.edit(targetPlaylist, items: tracksToAdd) Where targetPlaylist is of type MusicItemCollection<MusicKit.Playlist>.Element and tracksToAdd is of type [Track] The targetPlaylist was created, using new iOS16 way, here: let newPlaylist = try await MusicLibrary.shared.createPlaylist(name: name, description: description) tracksToAdd is derived by performing a MusicLibraryRequest on a specific playlist ID, and then doing something like this: if let tracksToAdd = try await playlist.with(.tracks).tracks {    // add tracks to target playlist } My problem is that when I perform attempt the edit, I am faced with a rather sad looking crash. libdispatch.dylib`dispatch_group_leave.cold.1:     0x10b43d62c <+0>:  mov    x8, #0x0     0x10b43d630 <+4>:  stp    x20, x21, [sp, #-0x10]!     0x10b43d634 <+8>:  adrp   x20, 6     0x10b43d638 <+12>: add    x20, x20, #0xfbf          ; "BUG IN CLIENT OF LIBDISPATCH: Unbalanced call to dispatch_group_leave()"     0x10b43d63c <+16>: adrp   x21, 40     0x10b43d640 <+20>: add    x21, x21, #0x260          ; gCRAnnotations     0x10b43d644 <+24>: str    x20, [x21, #0x8]     0x10b43d648 <+28>: str    x8, [x21, #0x38]     0x10b43d64c <+32>: ldp    x20, x21, [sp], #0x10 ->  0x10b43d650 <+36>: brk    #0x1 I assume that I must be doing something wrong, but I frankly have no idea how to troubleshoot this. Any help would be most appreciated. Thanks. @david-apple?

MusicKit failed retrieving tokens on Simulator.
Is anyone else receiving this warning from Xcode when running on the Simulator? "Failed retrieving MusicKit tokens: fetching the developer token is not supported in the simulator when running on this version of macOS; please upgrade your Mac to macOS Ventura." My Mac is already updated to macOS Sequoia, and I'm also running the latest version of Xcode. Feedback: FB17150538

MusicKit for Android reports an error when playing stations
我在使用 musicKit SDK for Android 1.1.2 时,发现 MediaContainerType 只定义了三种类型: 无 = 0; 专辑 = 1; 播放列表 = 2; 未定义 RADIO_STATION 类型。 但是,com.apple.android.music.playback.model 的文档指出支持 RADIO_STATION 类型。 此问题在我传入 stations ID 后会导致错误: MediaSessionManager com.apple.android.music.sdk.testapp D onPlaybackError() Quincy java.io.IOException 请问如何解决这个问题?

How can third-party iOS apps obtain real-time waveform / spectrogram data for Apple Music tracks (similar to djay & other DJ apps)?
Hi everyone, I’m working on an iOS MusicKit app that overlays a metronome on top of Apple Music playback. To line the clicks up perfectly I’d like access to low-level audio analysis data—ideally a waveform / spectrogram or beat grid—while the track is playing. I’ve noticed that several approved DJ apps (e.g. djay, Serato, rekordbox) can already: • Display detailed scrolling waveforms of Apple Music songs • Scratch, loop or time-stretch those tracks in real time That implies they receive decoded PCM frames or at least high-resolution analysis data from Apple Music under a special entitlement. My questions: 1. Does MusicKit (or any public framework) expose real-time audio buffers, FFT bins, or beat markers for streaming Apple Music content? 2. If not, is there an Apple program or entitlement that developers can apply for—similar to the “DJ with Apple Music” initiative—to gain that deeper access? 3. Where can I find official documentation or a point of contact for this kind of request? I’ve searched the docs and forums but only see standard MusicKit playback APIs, which don’t appear to expose raw audio for DRM-protected songs. Any guidance, links or insider tips on the proper application process would be hugely appreciated! Thanks in advance.

Ducking MusicKit output when playing another sound
I am developing an app that uses MusicKit to play music and then I need to have spoken words played to the user, while ducking the audio coming from MusicKit (application music player) the built in Siri voices are not off sufficient quality so I am using an external service to create an mp3 file and then play this back using AVAudioSession Sample code below the problem I am having is that .duckOthers is not ducking the Application Music Player output Is this a bug or am I doing this wrong? // Configure audio session for system-wide ducking try AVAudioSession.sharedInstance().setCategory(.playback, mode: .spokenAudio, options: [.duckOthers, .mixWithOthers]) try AVAudioSession.sharedInstance().setActive(true) // Set the ducking level to maximum try AVAudioSession.sharedInstance().setPreferredIOBufferDuration(0.005) // Create and configure audio player self.audioPlayer = try AVAudioPlayer(data: audioData) self.audioPlayer?.delegate = self self.audioPlayer?.volume = 1.0 // Ensure full volume for speech self.audioPlayer?.prepareToPlay() // Set the audio player's settings for maximum clarity self.audioPlayer?.enableRate = false self.audioPlayer?.pan = 0.0 // Center the audio self.audioPlayer?.play()

MusicKit - Skipping Forwards or Backwards does not update
Hello everyone, I am working on an app that allows you to review your own music using Apple Music. Currently I am running into an issue with the skipping forwards and backwards outside of the app. How it should work: When skipping forward or backwards on the lock or home screen of an iPhone, the next or previous song on an album should play and the information should change to reflect that in the app. If you play a song in Apple Music, you can see a Now Playing view in the lock screen. When you skip forward or backwards, it will do either action and it would reflect that when you see a little frequency icon on artwork image of a song. What it's doing: When skipping forward or backwards on the lock or home screen of an iPhone, the next or previous song is reflected outside of the app, but not in the app. When skipping a song outside of the app, it works correctly to head to the next song. But when I return to the app, it is not reflected NOTE: I am not using MusicKit variables such as Track, Album to display the songs. Since I want to grab the songs and review them I need a rating so I created my own that grabs the MusicItemID, name, artist(s), etc. NOTE: I am using ApplicationMusicPlayer.shared Is there a way to get the song to reflect in my app? (If its easier, a simple example of it would be nice. No need to create an entire xprod file)

Unable to Enable “Media Services (MusicKit, ShazamKit)” When Creating a Key
I am trying to integrate Apple Music API using MusicKit and need to generate a Developer Token. However, when I try to create a new key from the Certificates, Identifiers &amp; Profiles section, the “Media Services (MusicKit, ShazamKit, Apple Music Feed)” option is grayed out. We are getting the error 'there are no identifiers available that can be associated with the key.' Although we did checkmark 'musickit' in app services. I have already: Enrolled in the paid Apple Developer Program Created a valid App ID under Identifiers Logged in as the Account Holder Tried multiple browsers and devices Despite this, the option remains disabled. Could you please enable this or let me know what further steps I need to take? Thank you!
