What do you think are the top 10 worst music genres of all time?

Rap, dance, trance,kids music, r and b, hip hop, soul, pop, boy/girl bands, anything england chooses to use for eurovision (i mean, we got beaten by bloody jedward?!? Whats wrong with a AC/DC compared to an annoying pop group with a gay bloke asking if you want to suck on something?)
