You can't sort an array directly in Mongoose. You can clone the data and sort it as a JavaScript object by using toObject (documentation) and the Array sort method:

Playlist.load(function(err, playList) {
    var pl = playList.toObject();
    pl.musics.sort(function(m1, m2) { return m1.addedAt - m2.addedAt; });
    // pl contains the playlist now 
});
