ok, so I've had my Ipod for a while, and I want to move some of the songs around by chaging the album and stuff like that in info. The only problem is, I can't change some of the info. I right click the song, hit get info, and then when it comes up after I click the info tab, everything is gray and I can't edit it. I can change some of the newer stuff I put on the Ipod, but it's the older stuff that I need to format. Any clue how to change this, or what caused it?
