A few days ago I downloaded a few free songs from Walmart.com, but there was a little window that said they wouldn't work with iPod.
I tried to import them into my iTunes anyway, but it said it couldn't do it because of some kind of protection (even though I got the songs legally, dumb).
So I went around that, and burned the songs (with some others) onto a disc, and then uploaded that disc into my iTunes.
Yay!
