^ Yes I agree whole-heartedly.
Off the top of my head starting with the ones I hate the most.
Brokencyde (anyone who likes this band's "music" has no taste for music, imo)
Hollywood Undead
Waking the Cadaver
Linkin Park (phoney-angst ridden ****, no thanks)
Slipknot
Limp Bizkit (goes without saying)
Insane Clown Posse
Papa Roach
Whitechapel
Norma Jean
Underoath
Nickelback
Nirvana (I can tolerate grunge, but this band is overrated.)
Korn
Creed
Breaking Benjamin
Three Days Grace
Apocaltypitca
Theory of a Deadman
Seether
Shinedown
Senses Fail
Bring Me the Horizon (most girls are obsessed with this band)
Senses Fail
Panic at the Disco
My Chemaical Romance
Killswitch Engaged
As I Lay Dying (though they do have one good song.)
Darkthrone (yes I went there, talented I guess, yet bores me to death.)
most black metal, post-grunge, nu-metal, screamo/emo, and deathcore bands
Oh, and I'd add 99.9% of today's rappers, but this is the rock/metal section, so I'll leave it at that.
I guess you can say I hate just about anything that is either fake-angst ridden, or bands with cookie monster and/or screaming vocals.
There's probably more that I forgot to add, but I'll add them accordingly.
