Songs imported from a CD not authorized
I imported the album "Rare" by Selena Gomez last year from a CD I purchased and everything was fine up until recently when I tried listening to it on my phone, as I always do, and it kept skipping songs. I tried removing the songs off of my iPhone and resyncing them, and found that I couldn't play the songs on iTunes on my computer, as it kept saying my computer was not authorized to play them. Even after logging in and reauthorizing, it would give me the same message and I couldn't play them. I don't have the CD anymore so I can't reimport them and I don't want to completely delete the files.
