Indie rockers The Drums have slammed Kings of Leon despite previously supporting the band in London's Hyde Park. 

Jonathan Pierce, The Drums' frontman, told clickmusic.com that not only is 'Sex On Fire' "one of the worst songs I've heard in my life" he also thinks Britney Spears has more musical merit:

"They're very American bar rock and it's not interesting, it doesn't affect me at all. That 'Sex is on Fire' song is one of the worst songs I've heard in my life. I would advise them to split up and stop making music. I don't think they're really helping anybody - they've never made a song that's really touched me in any way."

"I honestly think that the new Britney Spears record is better than their songs - it sounds like a really great pop song and that's what I really like."

He also explained that he believes Jared Followill doesn't enjoy performing as part of Kings of Leon, adding:

"I do have to say that Jared was a very kind man and he's smarter than he's letting on. I don't think he really enjoys the music that Kings of Leon are putting out. I've had long conversations with him and he's very open to me. He has really great taste in music and likes really great bands - I think he looks at Kings of Leon and it's just a job that he has."

"I think that's a really sad place to be - going through the motions. To misrepresent yourself in a creative atmosphere seems a little dark to me."
