Bad Religion are very good, my favourite album would be "Stranger Than Fiction" though...I hope you've heard of the Ramones, THE best punk band, period!
Who hasn't heard the Ramones? They're awesome. Stranger Than Fiction is a cracking album, I was listening to part of it yesterday in fact! Another one of my favourite bands are the Clash, I have all their albums except for their last one.
Right now, I'm listening to alot of Psychobilly/Rockabilly, namely bands like Koffin Kats, Reverend Horton Heat, The Astounding Roy Gorbisons, Nekromantix, Stray Cats, stuff like that. Basically once I devour one music genre, only then do I move on to the next one
