The Strokes/Hives/Vines.... All besides that new Vines "Ms. Jackson" Cover
John Mayer
Nelly (Someone should cut up his face so he needs a whole box of those band-aids)
Nickelback (Thanks for ruining Roadrunner)
All Pearl Jam Wannabe Bands (Including the already mentioned Nickelback)
Linkin Park (Saw them open for Hed p.e. b4 they were on MTV... worst band i've ever seen live, including all small shows i've ever been to... must've somehow knew somebody to get signed... now that they have money, apparently they finally got some vocal training...)

All Pop-Punk
Most emo, but some of the actual talented stuff is good
Butthole Surfers
90% of all c0ck r0ck
Limp Bizkit (quit whining, i didn't like you when I saw you way back in the day... funny nobody liked you until a year after your album came out when you decided to make a video for faith...)
