@opusforlife2: Not really needed for such small changes.

@AliJavanJ1: Could you please rebase on dev and fixup your commits? Also, why would we want to disable shuffling as soon as the MainActivity gets destroyed?

Looks good to me, apart from the MainActivity change. Could you provide an explanation @AliJavanJ1 ? Otherwise I will revert that change and then merge, since the other changes look good. Thank you ;-)
