The argument could be made that “filthy” is relative. D12‘s “Shit On You” is probably more expletive-laden than Peaches‘ “Fuck the Pain Away.” Hell, anything Eminem ever did (especially, say, “Kim”, “’97 Bonnie & Clyde”, or “Guilty Conscience”) trumps the simple “beat da pussy up” retardation that is the Ying Yang Twins‘ “Wait.”
Shocking’s easy. Any asshat can string a series of offensive words togetehr and make a career out of it. *cough*Li’l John*cough* It takes talent to do something that’s shocking, vulgar, and actually has meaning beyond repeated profanity. Christ, Jack Grisham wrote “Code Blue” 25 years ago, and it’s still something I know I’m going to have trouble explaining to my kids when they get older.
