Worst Rock Band Ever !!!!

Who was/is the worst?
Korn, limp bizcut and kid rock, but i guess they don't really count as they claim to be rock bands but are really more like rap
All the disco ducks and coke-rockers from Saturday night Fever to the (not including) Specials.
I think so far we just have a sample of the posible bands that should be included. Starting in the '50s, but really taking off in the '70s....the marketing of a group began to have more to do with success than talent. Remember Milli- Vanilli (SP?)! Nothing has had more impact on this than videos. They took the focus away from music and marketing what was hot or trendy at the moment became the guiding light. Although all that said and done the real "death" by marketing, is now taking place in country music.
