*blink*
i do/have. rock is one of my favorite genres. Van Halen, Boston, Aerosmith, Creed... all very good bands, and all classic rock. but thanks for the suggestion anyways!!

my situation is the opposite of most people here: a lot of my favourite artists and songs ain't actually in my library, becoz i've never bothered to buy their songs. Examples of artists that should be in my library: Massive Attack, Nas, Kanye West
