Music I uploaded to iTunes from my own CDs won't play
I have over 3000 songs on my iTunes, and a number of them won't play. I have mix of stuff I purchased through the iTunes store, Apple Music, and my personal collection of a thousand CDs. The problem is on many of the songs I added from my CDs, iTunes is constantly asking me to authorize the computer. I put in my info, it processes, and then proceeds to skip the song. Tried a number of times with no luck. Most of these songs also say they are ineligible for the iTunes cloud. I don't get it. These CDs belong to me. Why is this constantly happening? What's the fix? Do I have to delete them completely from my library and reupload them? It's beyond frustrating.
