I buy CD's because I like having better sound quality on my iPod than a random YouTube mp3. Also, I can play them in my car too, without having to hook up an aux cable to my iPod. And once in a while I might buy an iTunes mp3, but only if there's one or two really good songs on a trash album. I don't illegally download, not so much for the morality aspect (although it is important to me that the artists get SOME profit from their creations), but for the better audio quality.
