Spotify App API: Play specific track from album

Question

Trying to play a specific track from an album with the player view. It works all good when using

player.play(objTrack, objTrack.album);

But

Answer 1

If you have the current track number I suppose you got it from a track object. Here is my way:

// trackObj <- The track object

var album = m.Album.fromURI('spotify:album:7Kmmw7Z5D2UD5MVwdm10sT', function(album) {
    var player = new v.Player();
    player.track = trackObj;
    album.get = function() {
        return trackObj;
    }
    player.context = album;
    document.body.appendChild(player.node);
});
