I am developing a SWIFITUI app that transfers playlists between Apple Music and Spotify but I am not directly create my requests to those companies APIs. I have my own backend. But when fetching users playlists due to "https://api.music.apple.com/v1/me/library/playlists" the response is 403 all the time. I tried many ways including creating new DevToken and UserToken when user login and sending those tokens in headers with Authorization and Music-User-Token. What else can be the problem? Note: My team ids in Xcode and apple developer portal seems different. Maybe this is the problem.

Hi there, I recently launched a dj app to the mac app store, and was wondering how I could access songs for mixing purposes via Apple Music just like how serato, rekordbox, djay, and other DJ apps do? Thanks, Gunek

Hi everyone, We’re currently developing a music-based app using MusicKit, and we recently noticed that iOS 26 beta introduces a new “Automix” feature in the Apple Music app. This enables seamless DJ-style transitions between songs—beyond the standard crossfade functionality. We’re trying to understand: Will this Automix feature be accessible to third-party apps that use MusicKit? If not available in the initial iOS 26 release, is there a plan to expose it through public APIs in a future update? Is there any technical documentation, WWDC session, or roadmap info regarding Automix support via MusicKit? This functionality would be a significant enhancement for our app, especially for intelligent audio transitions and curated playlists. Thanks.

Just updated my computer, phone, and dev tools to the latest versions of everything. Now when I run my app in a previously-working simulator (iPhone 16 w. iOS 18.5) I get: 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. Also: <ICCloudServiceStatusMonitor: 0x600003320e60>: Invoking 1 completion handler for MusicKit tokens. error=<ICError.DeveloperTokenFetchingFailed (-8200) "Failed to fetch media token from <AMSMediaTokenService: 0x6000029049a0>." { underlyingErrors: [ <AMSErrorDomain.300 "Token request encoding failed The token request encoder finished with an error." { userInfo: { AMSDescription : "Token request encoding failed", AMSFailureReason : "The token request encoder finished with an error." }; underlyingErrors: [ <AMSErrorDomain.5 "Anisette Failed Platform not supported" { userInfo: { AMSDescription : "Anisette Failed", AMSFailureReason : "Platform not supported" }; Anybody know what gives here? The Ventura message is absurd because I'm on Tahoe 26.1. The same code works on a physical phone running iOS 26.

I use htttps://api.music.apple.com/v1/me/library/playlists/${playlistId}/tracks to add tracks to a playlist I created. How do I DELETE tracks from the playlist? The documentation does not mention a method for this. I have tried calling DELETE methods in various combinations but nothing seems to work. Is this possible?

Hi, I’m an iOS developer building an app with an use case that needs advanced playback on Apple Music subscription streams, specifically: • Real-time tempo change (BPM) during playback — i.e., time-stretch with key-lock, not just crossfade. • Beat-matched transitions between tracks. From what I can tell, this capability seems to exist only for approved partners and isn’t available through public MusicKit. Question: What’s the official request path to be evaluated for that restricted partner entitlement (application form, questionnaire, NDA, or internal team/BD contact)? If the entitlement identifier is internal, how can I get my account routed to the right Apple Music team? For reference, publicly announced partners include Algoriddim djay, Serato DJ Pro, rekordbox (AlphaTheta), and Engine DJ—all of which appear to implement mixing features that imply advanced playback (tempo/beat-matching) on Apple Music content. I’d prefer not to share product details publicly for the moment and can provide specifics privately if needed. Thanks in advance!

Hello, I'm trying to write a shortcut using Toolbox Pro that gets triggered by an accessibility trigger and then favorites the currently playing song. It's working pretty well, but I noticed that for some artists, especially asian ones, it simply doesn't work. While debugging, I noticed that the tool uses the same song ID, artist ID, everything as it should to search for the song and favorite it. However, I noticed that Apple Music treats artists with romanized names as two separate artists! https://music.apple.com/br/artist/王菲/41760704 https://music.apple.com/br/artist/faye-wong/41760704?l=en-GB You can see that the ID is the same (41760704). It seems that, when I search for the artist, the first artist (王菲) returns, so that when I open URLs on the web for the artist I can see a star next to the song name, meaning that it got a like. However, the romanized artist (faye-wong) doesn't have a like on the same song. This is very weird, right?

If I fetch a library playlist like the generated "Favorites" playlist via MusicKit like this guard let initialTracks = try await playlist.with([.tracks]).tracks else { return nil } I get a list of tracks like this: ... TrackID: i.e5gmPS6rZ856 TrackID: i.4ZQMxU0OxNg0 TrackID: i.J198KH4P85K4 TrackID: i.J1AaRC4P85K4 TrackID: i.4BPqWt0OxNg0 TrackID: 4473570282773028026 TrackID: 4473570282773028025 TrackID: 4015088256684964387 TrackID: 4473570282773028024 TrackID: 7541557725362154249 TrackID: 4473570282773028027 I save the IDs for later use, but when I want to fetch them, only the ones with ids that starts with "i." work. static func getLibrarySong(from id: String) async -> Song? { var request = MusicLibraryRequest<Song>() request.filter(matching: \.id, equalTo: MusicItemID(id)) do { let response = try await request.response() return response.items.first } catch { ... } } Or the Apple Music API endpoint : static func getLibrarySongFromAPI(with id: String) async -> Song? { guard let url = AppleMusicURL.getURL(for: .getSongById, id: id) else { return nil } do { let dataRequest = MusicDataRequest(urlRequest: URLRequest(url: url)) let dataResponse = try await dataRequest.response() let response = try JSONDecoder().decode(SongsResponse.self, from: dataResponse.data) return response.data.first } catch { ... } } Both functions above won't work for the non numeric like 4473570282773028024 so it seems the ID is wrong, but how do I make it work? Otherwise I can fetch all the songs fine, in catalog or in the library, but these few songs can't be individually fetched, only with the try await playlist.with([.tracks])` fetch, that gets the whole playlist. But obviously this isn't always possible. Thanks in advance!

Hi there, I recently launched a dj app to the mac app store, and was wondering how I could access raw data to songs from apple music just like how serato, rekordbox, djay, etc. do? Thanks, Gunek

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.

Hey there, We're seeing a high rate of 403 - Invalid Authentication on this endpoint v1/me/library/artists since a few days. Does anyone have the same issue ?

I am using https://developer.apple.com/documentation/applemusicapi/add-tracks-to-a-library-playlist to add tracks to playlists. This endpoint works fine for all playlists except for collaborative playlists. For collaborative playlist I get the following 500 error as a response: "errors": [ { "id": "<some id>", "title": "Upstream Service Error", "detail": "Unable to update tracks", "status": "500", "code": "50001" } ] } Steps to reproduce: Create a playlist in your library. Use the api to add a song. Confirm that it works. Make that same playlist collaborative. Update the playlist ID in your api request (as making a playlist collaborative changes its id) Confirm that you get the 500 error.

add a currently playing track endpoint on the apple music api. its kinda wild how apple music goes after spotify without having such a useful endpoint.

Hi folks, I'm trying to generate a provisioning profile that includes both Healthkit and MusicKit entitlements. The healthKit pieces if fine, and included in the profile. However, despite selecting Musickit under services in the ID setup, the entitlement doesn't seem to be included in the profile. Other steps taken: Setup the app in App Store Connect, generated a media ID and Key. Tried both automatic and manual signing. Are there specifics tricks to getting this one to work?

Hi, I am looking for guidance on how to create a scrollable song list, such as the attachment. The song list was originally created in C#, using an RTF object and populated by about 43 lines of song criteria. What similar approach would I use in Swift and MacOS? By the way, I currently play music that resides on the Mac, no external streaming is required or desired. Thanks, Jim

My iPhone is on iOS 26 RC and when I tried adding music to my library, the app crashed and when I opened it again my whole Apple Music library including playlists disappeared but it still shows that the app is showing 8 gb of storage. I’ve tried restarting my phone, closed the app and reopened it, and that didn’t work, what do I do

I’m running HomePod OS 26 on two HomePod minis and OS 18.6 on main HomePod (original) I’ve enabled Crossfade in the Home app. I’m playing Apple Music directly in the HomePod mini. Crossfade just doesn’t work on any HomePod. I can understand it not working on the HomePod - but why isn’t it working on the minis running OS 26? I’ve tried disabling and enabling Crossfade, rebooting HomePods etc but nothing?!

Session player regions populate blank, with no sound media when tracks or regions are created.

When I attemp to Play song using apple Music api I get this error> I have put in the privacy string. Do I need to generate a token?
