Unable to play any of my Christmas playlist in Apple Music

I've suffered through iTunes (as it USED to be known) since it first came out. I always defended it and just kept on plowing on through. NOTHING that ever happened in all those years . My own playlist on my library are TRASHED. I can't even listen to my Christmas playlists. To be honest? I've never found that any of these 'fixes' work - at least not for me and I've been trying them for years. Even if I try to MANUALLY play a song in MY library - it plays some other song. Does anyone have any REAL information about what's going on and if there is REALLY a fix to this? Hate to think I'm not going to listen to ANY of my Christmas playlists that have taken me years to build. (sorry, Apple)
