I rarely listen to anything outside of the 70's or 80's, but as far as rocking songs go:
The Dead Kennedys-Kill The Poor
The Misfits-One Last Caress and Return of the Fly
The Buzzcocks-Ever Fall In Love With Someone
Bad Religion-Shattered Faith
The Sex Pistols-No Feelings
Tiger Army-Valley Of Dreams
The Damned-New Rose and Democracy
The Germs-Sex Boy, Forming, and Lexicon Devil
On another note, UnknownEric speaks the truth. 75% of today's music scene sucks my left nut. They shouldn't be allowed to touch the classics, especially one like The Cure's "Love Song". And for the record: I truly believe that 311, the dumbfucks who remade "Love Song", are the worst band ever. Flame if you wish, but these guys just go around ruining music for everyone. They are an embarrassment to Rock and Reggae.
PS: AFI's new stuff is really good. They went deeper than being a cliché punk-sk8-hardcore band. Some people just dont have an open mind, or possibly the brainpower to understand any song that doesnt have the word "Fuck" nowadays.

I guess I'll just have to settle for saying cocksucker a lot.
