It was P.O.D actually. And yes, Limp Bizdick sucks balls, but I really don't mind Linkin Park and Saliva's not "rappish" as far as I know.
You could ask the same question of all the "hey look at my car from fifty different angles and then watch me race someone on the freeway" videos that get posted daily on the Internet and are ALWAYS accompanied by shitty rap music...
