All of a sudden, a "!" has appeared in front of a lot of my iTunes songs and it says that the original cannot be found. What happened? And what do I do now?
A week ago, I was burning CDs, no problem. This week, I tried to burn a CD from the same playlist, but all of the songs now have a "!" in front of the title. When I click on it, it says that the original cannot be found. More and more of the songs are having this same "!" showing up. What happened? And how do I get the music back? There are thousands of songs with this "!"!!!!! And, I'm a music teacher, so this is my life!
