Hello, i have been iTunes since v1. And ive had an iPod since they came out. Lately I have noticed that in iTunes some of my songs are disappearing. They arent disappearing from my iTunes library, but from the computer. I'm not deleting them, they are just gone. so i have a few questions... 1) is there an easy way to tell which songs are in ur library. when a song is missing i get a little circle with an explanation mark inside of it. how do i check for songs like that. and secondly, has anyone else been having this problem?
