Play specific song

Question

I am looking at ways to store song information and then play a specific song. I've seen this post: How do you use MPMediaItemPropertyPersistentID to play music in iPhone Music Player Framework?

If I have a MPMediaItemPropertyPersistentID already, can I directly play that song without looping every single song until I find a matching id?

You don't have to do this by looping through all the items in the library. It can be done via MPMediaQuery, something like this:

NSNumber *persistentIDNumber = [NSNumber numberWithInteger:4238475234];

MPMusicPlayerController *player = [MPMusicPlayerController applicationMusicPlayer];

MPMediaPropertyPredicate *predicate = [MPMediaPropertyPredicate predicateWithValue:persistentIDNumber forProperty:MPMediaEntityPropertyPersistentID];

MPMediaQuery *query = [[MPMediaQuery alloc] init];

[query addFilterPredicate: predicate];

[player setQueueWithQuery:query];
[player prepareToPlay];
[player play];
