Puff Diddy, or whatever the hell he wants to call himself, in fact the entire 'bling r&b/rap' genre, fuck it pisses me off more than just about anything! Possibly more than Nickelback!
That dude with the dreadlocks who sang that "Mr Jones" song in the 90s.
Metallica, overrated, boring crap.
Most any boy band with the exception of Take That!
