A couple of weeks ago I got help here to play one song and the solution to my problem was that I wasn't adding the song (Track Type) to the queue correctly, so now I want to be able to add a playlist worth of songs to the queue. The problem is when I try to add an array of the Track type I get an error. The other part of this issue for me is how do I access an individual song off of the queue after I add it? I see I can do ApplicationMusicPlayer.shared.queue.currentItem but I think I'm missing/misunderstanding something here. Anyway's I'll post the code I have to show how I'm attempting to do this at this moment.

In this scenario we're getting passed in a playlist from another view.

import SwiftUI
import MusicKit

struct PlayBackView: View {
	@State var song: Track?
	@State private var songs: [Track] = []
	@State var playlist: Playlist
	
	private let player = ApplicationMusicPlayer.shared
	
	VStack {
		// Album Cover
		HStack(spacing: 20) {
			if let artwork = player.queue.currentEntry?.artwork {
				ArtworkImage(artwork, height: 100)
			} else {
				Image(systemName: "music.note")
				.resizable()
				.frame(width: 100, height: 100)
			}
			
			VStack(alignment: .leading) {
				// Song Title
				Text(player.queue.currentEntry?.title ?? "Song Title Not Found")
				.font(.title)
				.fixedSize(horizontal: false, vertical: true)
			}
		}
	}
	.padding()
	.task {
 		await loadTracks()

         // It's Here I thought I could do something like this
        player.queue = tracks

        // Since I can do this with one singular track
        player.queue = [song]
		
		do {
			try await player.queue.insert(songs, position: .afterCurrentEntry)
		} catch {
			print(error.localizedDescription)
		}
	}
}

@MainActor
	private func loadTracks() async {
		do {
			let detailedPlaylist = try await playlist.with([.tracks])
			let tracks = detailedPlaylist.tracks ?? []
			setTracks(tracks)
		} catch {
			print(error.localizedDescription)
		}
	}

	@MainActor
	private func setTracks(_ tracks: MusicItemCollection<Track>) {
		songs = Array(tracks)
	}

}

Hello @JB184351, you asked:

[...] so now I want to be able to add a playlist worth of songs to the queue.

If you have a Playlist, you can take advantage of the init(playlist:startingAt:) initializer. For example:

let request = MusicLibraryRequest<Playlist>()
let response = try await request.response()

if let firstPlaylist = response.items.first, let firstEntry = firstPlaylist.entries?.first {
    player.queue = .init(playlist: firstPlaylist, startingAt: firstEntry)
}

Your other question was:

The other part of this issue for me is how do I access an individual song off of the queue after I add it?

Please see this forum post for a detailed answer. In short, since you are using ApplicationMusicPlayer, you can get all its entries.
