Apple Music shuffle not random
When I shuffle songs in my music library, 80-90% of the songs are taken from a selection of maybe 15 albums. If a song isn't in one of those albums, it is almost never played. The songs that are played repeatedly are from albums that constitute only a small percentage of my library. I have tried closing and reopening the app. I have tried shutting off the phone and turning it ]back on. For reasons unrelated to this problem, I had to do a factory reset of my iPhone. Nothing has any effect.
