I have a playlist in Music.app that contains over a thousand songs. My iPhone doesn't have enough storage to accept all of them without deleting apps. So I created another playlist that says to take twelve hours worth at random.
Unfortunately, at every sync, it gets the same list of songs. The only ways I can think of to get a different random sample is to delete and re-create the playlist, or to change random to something else and change it back.
Is there some other simple trick to make it re-do the random sample at each sync?
