I often find when doing basic actions in MusicKit it is incredibly slow compared to Apple's Music App. I've tried different versions, devices, networks, Apple's sample code, it all throughout the last several years, and it is all the same. Does anyone else have this issue?

I can't seem to find an album using MusicKit containing RecordLabel. I am using album.with([..., .recordLabels, ...] but I only see an empty recordLabels collection returned for every album I am trying... Is this actually available / populated through MusicKit?

Hello, I am working on the Musickit web browser application. I have created my developer token as mentioned in the documentation. When I call the authorize() method to authenticate, I get the Apple Music pop up as expected. However, after entering the user credentials and "allowing" access, I get the following error: POST https://play.itunes.apple.com/WebObjects/MZPlay.woa/wa/webPlayerLogout 403 (Forbidden) musickit.js:28 Uncaught (in promise) AUTHORIZATION_ERROR: Unauthorized at https://js-cdn.music.apple.com/musickit/v3/musickit.js:28:269512 at Generator.next () at asyncGeneratorStep$u (https://js-cdn.music.apple.com/musickit/v3/musickit.js:28:266594) at _next (https://js-cdn.music.apple.com/musickit/v3/musickit.js:28:266821) I am using an user account with paid subscription to Apple Music. With the JWT created, I am able to make API calls and receive the response for requests that do that need the userToken. I am currently stuck at this step and would like some help to root cause this issue.

Hi! For a couple of days and only for some users, we are getting this error message on this endpoint: https://api.music.apple.com/v1/me/library/playlists?limit=100 {"id":"6NT5LBXIZW65K2G3L6QY3WWYAA","title":"Upstream Service Error","detail":"Error fetching library content","status":"500","code":"50001"} Any idea?

I am working on a radio app. This is the first time and I have a problem with lock Screen Audio Card. According to docs It looks ok but could you please check why I can not display Audio Now Playing Card on lock Screen. 2 Code samples, 1. Now Playing and 2. Logic of current song and Album art. 1.

I am currently experimenting with the MusicKit API, specifically if/how it could replace iTunesLibrary on macOS and MediaPlayer on iOS. My question is specifically about DRM-free tracks that the user has available locally (e.g. purchased, matched or uploaded tracks): Is there a way to access the on-disk URL of locally available and DRM-free tracks? In the iTunesLibrary framework on macOS there is ITLibMediaItem.location and on iOS I can get this path via MPMediaItem.assetURL, but MusicKit's Song.url seems to be nil for all of these tracks in my tests.

Hey there, I have been trying to add the ability for a user to edit the playback rate of a song in their Apple Music library to my application. I have found that whenever the playback rate is changed, the music pausing for about half a second. I was wondering what the cause of this issue is and if there is anyway around it. For context I am using the SystemMusicPlayer from MusicKit.

I can not find an album where isCompilation is true, even when the album clearly consists of "songs by various artists". For example: Album( id: "567979803", title: "Earth's Answer", artistName: "Brian Keane, Deuter, James Newton, ,...many more", isCompilation: false The compilation checkbox for this album in the Apple Music Catalog Get Info dialog is also not checked. Is this field NEVER SET in the catalog or the MusicKit API? If there IS an album where isCompilation is true, I'd like its ID to use for a test case. If not, can this be added to the API?

Running in a Mac (Catalyst) target or Apple Silicon (designed for iPad). Just accessing the playbackStoreID from the MPMediaItem shows this error in the console: -[ITMediaItem valueForMPMediaEntityProperty:]: Unhandled MPMediaEntityProperty subscriptionStoreItemAdamID. The value returned is always “”. This works as expected on iOS and iPadOS, returning a valid playbackStoreID. import SwiftUI import MediaPlayer @main struct PSIDDemoApp: App { var body: some Scene { WindowGroup { Text("playbackStoreID demo") .task { let authResult = await MPMediaLibrary.requestAuthorization() if authResult == .authorized { if let item = MPMediaQuery.songs().items?.first { let persistentID = item.persistentID let playbackStoreID = item.playbackStoreID // <--- Here print("Item \(persistentID), \(playbackStoreID)") } } } } } } Xcode 15.1, also tested with Xcode 15.3 beta 2. MacOS Sonoma 14.3.1 FB13607631

Is there a way to retrieve a list of all the favorited artists for a given user via the Apple Music API? I see endpoints for playback history and resources added to the library. But I want to retrieve the full list of favorited artists for the given user and I don't see any obvious choices in the documentation. Thanks in advance!

My app is consistently crashing for a specific user on 14.3 (iMac (24-inch, M1, 2021) when their library is being retrieved in full. User says they have 36k+ songs in their library which includes purchased music. This is the code making the call: var request = MusicLibraryRequest<Album>() request.limit = 10000 let response = try await request.response() I’m aware of a similar (?) crash FB13094022 (https://forums.developer.apple.com/forums/thread/736717) that was claim fixed for 14.2. Not sure if this is a separate issue or linked. I’ve submitted new FB13573268 for it.

Not sure when it happened but I can no longer play explicit songs in my app using MK v3. I've turned off restrictions/made sure i have access to explicit in... My phone (Screen Time) My computer (Screen Time) My iPad (Screen Time) music.apple.com (Settings) and I still get this error when I try to play a song in console. `CONTENT_RESTRICTED: Content restricted at set isRestricted (https://js-cdn.music.apple.com/musickit/v3/musickit.js:28:296791) at SerialPlaybackController._prepareQueue (https://js-cdn.music.apple.com/musickit/v3/musickit.js:28:318357) at SerialPlaybackController._prepareQueue (https://js-cdn.music.apple.com/musickit/v3/musickit.js:28:359408) at set queue (https://js-cdn.music.apple.com/musickit/v3/musickit.js:28:308934) at https://js-cdn.music.apple.com/musickit/v3/musickit.js:28:357429 at Generator.next (<anonymous>) at asyncGeneratorStep$j (https://js-cdn.music.apple.com/musickit/v3/musickit.js:28:351481) at _next (https://js-cdn.music.apple.com/musickit/v3/musickit.js:28:351708)`

I am trying to retrieve same information about a song as is available on the music.apple.com page (see screenshot). It seems neither MusicKit and/or Apple Music API's deliver that depth of information. For example, the names listed for Production and Techniques. Am I correct?

Is it possible using MusicKit API's to access the About information displayed on an artist page in Apple Music? I hoped Artist.editiorialNotes would give me the information but there is scarce information in there. Even for Taylor Swift, only editorialNotes.short displays brief info: "The genre-defying singer-songwriter is the voice of a generation." If currently not possible, are there plans for it in the future? Also, with the above in mind, and never seen any editorialNotes for a song, is it safe to assume editorialNotes are mainly used for albums?

struct AlbumDetails : Hashable { let artistId: String? } func fetchAlbumDetails(upc: String) async throws -> AlbumDetails { let request = MusicCatalogResourceRequest<Album>(matching: \.upc, equalTo: upc) let response = try await request.response() guard let album = response.items.first else { throw NSError(domain: "AlbumNotFound", code: 0, userInfo: nil) } do { let artistID = try await fetchAlbumDetails(upc: upc) print("Artist ID: \(artistID)") } catch { print("Error fetching artist ID: \(error)") } return AlbumDetails(artistId: album.artists?.first?.id) with this function, i can return nearly everything except the artist ID so i know its not a problem with the request but I know there has to be a way to get the artistID, there has too. If anyone has a solution to this I would reallly appricate it

As the title states. Would like to use MusicKit for Web instead of the Swift integration.

Hi! I've been working on a project in python that pulls in a bunch of my personal apple music playback history and library, etc. I can't find a single good/functional example on how to pull the Music User Token via the android method or MusicKit JS (web) - I've spent a lot of hours on this today, and no permutation of existing examples/documentation has worked. Any guidance would be much appreciated!! If you have a web app that pulls the music user token, I just need help understanding how to get to the token itself. Thank you!

I'm writing an Android app that uses the Apple MusicKit SDK for Android. I am trying to understand how to handle the Apple Music user token, once I got it from authentication flow. I don't know when the token will expire, it is not a regular jwt token, so I cannot check the expiration date. And I don't want to run the auth flow on every app run, it will be annoying for the users. Any guidance on how to handle and invalidate apple music user tokens?

I have downloaded the official Apple MusicKit SDK for Android and integrated 2 AARs it has in my app (musickitauth-release-1.1.2.aar and mediaplayback-release-1.1.1.aar). When I try to build my app I'm getting an error: Manifest merger failed : android:exported needs to be explicitly specified for element <activity#com.apple.android.sdk.authentication.SDKUriHandlerActivity>. Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined. See https://developer.android.com/guide/topics/manifest/activity-element#exported for details. Which makes sense, since when I look into the AAR's AndroidManifest.xml I see that this is missing in SDKUriHandlerActivity. Can this be fixed?
