Why are my songs greyed out?
Okay, so the other day, I was downloading new songs onto my iPad 2 but, my computer froze and it deleted all the songs on my iPad. So, I decided to re-download all of them, but whenever I do, the songs appear to be greyed out. It also has a little symbol on the side that looks like a refresh button. It won't let me play the greyed out songs that I tried to download onto my iPad, but it does play when I play it from my iTunes library. So, my question is, how do I fix the problem? & what is causing it?
iPad 2, iOS 5.1.1
