Awful. playlists already downloaded regularly corrupt & I get a downloading icon on them. I don't like the way views have separate tabs for youtube music and uploads - needs a third tab for "both" so I could e.g. shuffle all songs by 1 artist whether uploaded or in my library. Update - now deleting/losing my uploaded songs but I don't know which as it just says it (says video not song!) and doesn't give details. So how am I meant to tell which songs of mine it's decided to ditch? Dreadful!
