If old means stuff you listened to in the past then Iron Maiden, Guns N' Roses, Soundgarden and maybe some other stuff. There are some stuff I listened to once that I don't really listen to anymore (although I don't think it's crap), like RUN-DMC, The Danish equilivant MC Einar, other rap stuff, Nirvana, Gorky Park (although "Bang" is good for drinking) and probably some more. When I was five or something my dad gave me some tapes with Boney M, Cliff Richard and some Danish artists called Bamse and Shu Bi Dua. "Rasputin" by Boney M is alright (although it's gotten tiresome), but I don't listen to the rest.
If old means older music, well I almost don't listen to anything newer than the 70's, so don't get me started there!
