Hi, is there a way to display the animated cover art in an app? Not every album has a cover art but for the ones that have one I would like to display them instead of the artwork. Thank you :)

I need to duck the audio coming from ApplicationMusicPlayer while playing a local file using AVAudioPlayer. I've tried using the duckOthers option as follows, but it doesn't work: let appAudioSession = AVAudioSession.sharedInstance() do { try appAudioSession.setCategory(.playAndRecord, mode: .default, options: .duckOthers) Maybe this is because there's one session for the entire app, and ApplicationMusicPlayer is using it? This is a fairly critical problem for my application, since Music content is always much louder than locally recorded content. Any insight appreciated.

I filed FB13689023 for this since it is clearly unexpected. Non Apple Music library tracks are not returned on macOS using MusicLibraryRequest. I tried querying by artist where I only get Apple Music tracks, and by id where I don't get the track. On iPhone and iPad I was able to get both AM and non-AM tracks, that's how I got a valid id to try on macOS. Sync Library is on. The build targets My Mac (Designed for iPad). I'm using Xcode 15.3 and I'm on Sonoma (14.4). Any help is appreciated...

I'm trying to find a library item by title and artist but it returns 0 items. Example below for existing track in my library. With title filter commented out, it successfully gives me all library items for that artistName. If I add the title filter, or have only the title filter, I get 0 items. Why is that? var request = MusicLibraryRequest<MusicKit.Track>() // request.filter(matching: \.title, equalTo: "Crises (Remastered 2013)") request.filter(matching: \.artistName, equalTo: "Mike Oldfield") let response = try await request.response() I can find the track by filtering the returned tracks by artist, but I feel this might not be an ideal approach if I have a bunch of tracks to find, possibly by different artists. The reason I'm not querying by id is that I'm planning to do this sort of query for non Apple Music items and if I'm not mistaken there is no cross-device id for those (even with Sync Library on). If I have the app on multiple devices with the same Apple ID looking at the same library, I want device 2 to find the track you interacted with on device 1. If there are better ways to solve this, any ideas are welcome. Appreciate any help.

I was about to finally sign up for the Apple Music affiliate program since one of my apps does provide the MusickKit Subscription Offer. However, it looks like it was renamed and restricts usage to only artists and record labels. (https://partners.applemediaservices.com) Is this correct? Can I as an indie developer not earn commission of Apple Music that I drive from my apps?

After thoroughly scouring the internet numerous times, I came to the realization that Apple has not documented their User Authentication flow. Instead, developers are often directed to use their JavaScript solution, which proves to be insufficient and impractical for many projects. Could we please request a comprehensive documentation outlining the process of generating a Music User Token from the Developer Token? This would greatly benefit developers seeking to integrate Apple Music functionality into their projects.

Hello everyone, my name is Joshua Osagie. For 2 months now, I have been trying to build my own music application, but unfortunately, I can’t because I was thinking I would get an API from maybe Apple Music or Spotify that will grant me access to over 100 million music. Even if the API is paid for, I have been doing my research, but then it's kind of impossible. So please, if anyone has an idea on what I can do to bring this application to life, I will really appreciate it. Or if anyone could share me an idea on how to get over millions of music on my app, I will be really grateful.

I'm working on an application that aims to deliver a DJ-like experience by overlapping songs and implementing volume fading. During development, I've encountered a roadblock due to the MusicPlayerController singleton behavior in iOS, which seems to only support playback of one audio stream at a time and doesn't support overlapping of songs or fading volume between tracks. I understand that Apple Music content is protected and that playback through Apple MusicKit must respect the DRM and licensing agreements. However, I've noticed an application called "Mixonset" that seems to be able to stream songs from Apple Music, use the music player, and create an overlapping effect of songs for users. Could anyone share insights on how Mixonset might be achieving this within the constraints of the Apple MusicKit? Is there any approach that I could explore to implement similar functionality, such as overlapping songs or crossfading while adhering to Apple's guidelines and without violating any terms of service? Any advice or direction towards documentation and API capabilities that could support these features would be greatly appreciated. Thank you for your assistance.

Hi everyone! Are there any plans or existing alternatives to include the date a track was added to a playlist within Apple Music's API[1]? This functionality exists on Spotify[2] (with their "added_at" attribute), and it would be helpful for ordering tracks retrieved from playlists. Thank in advance for any help!

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.

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.
