I hate Ke$ha with the ignorant dollar sign the most, she's completely autotuned, has no meaning behind her music whatsoever and wants to do nothing other than get laid and party because she's famous. Post which mainstream artist you hate the most.

gaga sucks the most. her songs are retarded and shes a fucking slut thats not hot. her music is meaningless also.

also beiber gets a special mention for being canadian xD

Ke$ha ment for the $ to be ironic because she grew up poor but it's rather dumb

I really dislike Lady Gaga but I think I dislike those mainstream artists who I can't even remember the names of more like Trey Songz or whatever (and the 19 people who sound just like him)

Oh wait I forgot Rhianna she might be top spot

Rihanna is a gigantic tryhard, she appearantly is a "rockstar", when she's just a whore of a popstar. Robert Planet = rockstar, Rihanna = poser.

Haha yes yes of course! I also hate pizza bagelz

OMG new cher lloyd song is awesome!
JK lol, A7x all the way :D

Every. Fucking. One. Of. Them. Whenever I hear it I cringe and look in disgust, then leave.

Pretty much every time I get into a car that I'm not driving, i have headphones in, Justin Beaver should get vocal surgery (or a sex change), that auto-tuned dog Ke$ha should die, and Lady Gaga is meh. My most hated singer is Rebecca Black.

LADY GAGA! I'm filled with absolute disgust whenever I hear the crap she calls music!

Ke$ha and Rihanna definitely. Might throw Chris Brown in his clones in as well.
