I was reading a previous music thread and Nirvana got a mention and it got me thinking which bands really grate on me.
Here's my top three.
Nirvana.
The Beatles
Bruce Springsteen.
Feel free to lynch any band you dislike!

Queen (Over rated pretentious crap)
Muse (Over rated Queen wanabees)
Coldplay (goes without saying)
Sex Pistols (YOU DID NOT INVENT PUNK)

Muse: first two albums were good then they disappeared up their own backside

Red Hot Chilli Peppers: Horrible band

Biffy Clyro: Terrible name, terrible music

I could sit for hours and create a huge list but here's a few for now....

Tenacious D - Awful, awful band. Only famous because of Jack Black. I'd even go as far as saying they are talentless but that would be a compliment.

Glee - Not a band I know, but a music ensemble. Enough said really.

Anything off the XFactor - A living breathing walking abortion.

The wombats - his voice just goes through me
The darkness - just cant stand them

My hatred of the Beatles is well documented.

Others include but not exclusively;
Train
Oasis
Coldplay
Fightstar
Train
Chris Martin
Chris Martin's parents
Mumford and Sons
Chris Martin's ancestors
Train
The Script
Maroon 5

I could be here all day.

Rush
Coldplay
Franz Ferdinand
21st century Metallica
The Band
MCR
Fall out Boy

Coldplay
Coldplay
Coldplay

Paul Weller too.

Had his day with The Jam. Went a bit wonky with The Style Council, totally vanished up the sense of his own importance when he went solo.

REM
White Stripes
Radiohead
Next??
