The question could also be: Why would a label want to have a track on their compilation that is anyway gonna be released on an album...that is what it is about, you can think it as a single like in the pop music industry if you like, or a long clip for the album or two bonus tracks (the album is 75 minutes long) or actually whatever comes to your mind
