hey, I'm a n00b to iTunes and just recently had it installed. I uploaded all of my songs into the library and as it turns out, most of the song info was messed up. Like the help document said, I went to "Get Info" and then went to the "Info" tab and found the song info. The problem is that on some songs the song info is greyed out and the program won't let me change it. This is especially annoying since the "greyed out" songs' song info is inaccurate. How do i "ungrey" it so that I can change it?
