The "Classics" that make me ralph:
Rush
Journey
REO SpeedWagon
Boston
Jethro Tull
Later stuff that makes me puke:
Anyone who does that DeathMetal schlock. Sounds like a bunch of posturing apes.
Anyone who screams through the whole song. At least if you're gonna scream, have a decent sounding voice to begin with. Screaming like an ass continually isn't singing or clever or lyrically satirical. It's just crap.
Any BoyBand that claims to be a rock band.
I'm sure there's more but I feel all bitchy now so I should stop, LOL. Thanks for this thread though. It was fun. If I think of more, I'll be back.
