Getting the album title from the queue's current entry item

I'm trying to get the album title from the current entry in the Queue of ApplicationMusicPlayer.

I'm using the following code for this purpose -

let queue = ApplicationMusicPlayer.shared.queue
let item = queue.currentEntry?.item
 
if case let .song(song) = item {
  print(song.albumTitle)
}

But it is returning a nil value. If I print the debug description of the song, I get the other details.

Song(
  id: "1524813873",
  title: "'Til We Die",
  artistName: "Slipknot",
  discNumber: 1,
  hasLyrics: "false",
  releaseDate: "2008-08-20",
  trackNumber: 15
)

If I do a request to MusicCatalogResourceRequest<Song>, and print the debug description, I get the album title as well.

let queue = ApplicationMusicPlayer.shared.queue
let item = queue.currentEntry?.item
 
if case let .song(song) = item {
  do {
    let musicRequest = MusicCatalogResourceRequest<Song>(matching: \.id, equalTo: song.id)
 
    let response = try await musicRequest.response()
    print(response.items.first.debugDescription)
  } catch {
    print(error)
  }
}

Song(
  id: "1524813873",
  title: "'Til We Die",
  albumTitle: "All Hope Is Gone (Deluxe Edition)",
  artistName: "Slipknot",
  composerName: Chris Fehn, Corey Taylor, Craig Jones, Jim Root, Joey Jordison, Mick Thomson, Paul Gray, Shawn "Clown" Crahan & Sid Wilson,
  discNumber: 1,
  duration: 345.693,
  genreNames: [
    "Metal",
    "Music",
    "Rock"
  ],
  hasLyrics: "true",
  isrc: "NLA320887352",
  releaseDate: "2008-08-20",
  trackNumber: 15
)

Is this a bug or intentional? Thanks!
