Play all songs in music

Question

I have this code to play all songs in music library (added via iTunes and downloaded in library from Apple Music). I can not have just the songs. What am I doing wrong?

-(IBAction)playAllSongs:(id)sender {

  MPMediaQuery *songsQuery = [MPMediaQuery songsQuery];
  NSArray *songsArray = [songsQuery collections];

  MPMediaItemCollection *items =  [MPMediaItemCollection collectionWithItems:songsArray];
  MPMusicPlayerController *musicPlayer = [MPMusicPlayerController systemMusicPlayer];
  [musicPlayer setQueueWithItemCollection:items]; 
}

Answer 1

I solved my self

MPMediaQuery *songsQuery = [MPMediaQuery songsQuery];
NSArray *songsArray = [songsQuery items];

MPMediaItemCollection *items =  [MPMediaItemCollection collectionWithItems:songsArray];
MPMusicPlayerController *musicPlayer = [MPMusicPlayerController systemMusicPlayer];

//[songsQuery addFilterPredicate:[MPMediaPropertyPredicate predicateWithValue:[NSNumber numberWithBool:NO] forProperty:MPMediaItemPropertyIsCloudItem]]; // for iTunes Match or Apple music to exclude or not songs not in the device

[musicPlayer setQueueWithItemCollection:items];

Answer 2

The above answer works but it's a roundabout way to do it. A simpler way:

MPMediaQuery *songs = [MPMediaQuery songsQuery];
MPMusicPlayerController *musicPlayer = [MPMusicPlayerController systemMusicPlayer];
[musicPlayer setQueueWithQuery:songs]
