In no particular order
Coldplay - Peter Griffin put it best when he described them as "whiney bullcrap" I was talked into buying Parachutes and half way through my first listen of it I wanted to chew my own ears off. I've been told that I just don't appreciate the genius of them, well I'm happy to be unappreciative.

Meatloaf - How the hell can anyone listen to this bilge with a straight face, overblown, over-produced, cod-operatic bilge. At least Queen & The Darkness did it with their collective tongues firmly implanted in their cheeks. But everything from the rotund new-Wagnerian balladeer makes me want to punch glass.

Pendulum - Less variation in their songs then Teh Quo, end of.

UB40 - Music created by a mad scientist to be played at dinner parties by white, middle-class dinner-party types to show just how diverse they are by listening to reggae. F**k Off, this bears as much resemblance to reggae as Bon Jovi does to Norwegian Black Metal

Blck Eyed Peas (especially will.i.am.a.talentless.arsehole) - When you have to auto-tune your raps then there's no hope.

Muse - What happens when posh kids get guitars instead of violins. Dear education system, never let this happen in any school again.

agreed
especially re UB40, spent a month in jamaica about 10 yrs ago, stayed with family so we were 'in the sticks' and their songs were playing everyfuckingwhere...in the shops..on the radio..in taxis..comin out of peoples houses - for some reason at the time they loved them out there (dunno bout now, the chance they're still as popular is one reason i dont wanna go back) - oddly the first bob marley i heard was two weeks in to the holiday and at a very touristy beach...still puzzles me now
