Song shuffling has been broken for ages now. It used to work correctly, like shuffling and dealing a deck of cards, only reshuffling and redealing when the entire deck has been dealt (or the user initiates a reshuffle).. Now it's just randomly jumping around a playlist, sometimes playing the same song more than once before all the songs are played once. I have a feeling that money is involved somehow, as with everything else that's been enshittified.
