Apple Music - One CD Associated with 328 Songs
Somehow the data in Apple Music has gotten scrambled to where the Robert Plant / Alison Krause album Raising Sand now is associated with 328 songs. I have more than 3,000 songs and others artists may be incorrectly identified or have other bad info. These songs were all or almost all transferred from CDs I own, originally on a PC, but itunes / apple music worked okay on my ipad and phone until I got the macbook air and possibly until the Big Sur update.
How do I fix? As near as I can tell, the song titles are correct, but I don't know who the artists are in some cases and certainly don't want to fix 328 songs one by one.
