No fighting, just mention the names of the bands or musicians whom you think to be crappy, why do you hate them (insult the bands, if you may)...
Metallica - Don't ask, I just freakin' hate them. I hate Cowboy Accent (obviously referring to Metallica's vocalist who's name I did care to remember as it would eat a few bytes of my memory; maybe it would be a virus or worm or trojan in there - so, Shift + Delete). And I also fucking hate Lars Ulrich's drumming. Who qualified him as a drummer? Who did it? Step forward! However, I do give my salutations to the guitarists and the tunes, which is worthless if I don't like the vocalist and the drummer.
Mnemic - Noted as Metallica's favorite band, born is the largest crap the world of music has ever egested, Mnemic is nothing more than that. I didn't have the patience to listen to the full album - they just repeated the same "UUUAAAHHHGGGHHH" growl throughout each and every song of the entire "Passenger" album! FUCKH!
Hannah Montana - Do you need an explanation for it? DO YOU!!! HUH!!! Did you see her face recently? One of her cheeks is displaced!
Evanescence, Epica and Stream Of Passion - Oh God! I hate Goth music so fucking much that I can't begin to explain! What's wrong with these bands! This aren't the medieval times! This isn't Lord of the Rings or Eragon movies! Why do you give such retarded choruses!
Craig Mibbett (Blessthefall vocalist) - EMO! A FUCKING EMO! I've never heard a more emo vocalist in my entire career as a listener!
Matt Tuck (Trivium vocalist and guitarist) - As a guitarist, he kicks ass! But as a vocalist, GAWD, he's gay! He's Gay, I tell you! He started experimenting with his vocals with different types of growls. The ultimate consequence was that he became a gay beyond no return.
Simple Plan - Please, no more Emo-ish Punk Rock bands! Please, I beg you! They all sound the same! I asked one of my friends who happens to be big fan of Simple Plan: "Hey dude, bring me ONE SP song that doesn't sound the same as the others?". It took him about three days to listen to all the songs over and over again and bring me ONE somewhat different song. He: "Here, I give you ONE SP song which doesn't sound like the others". Me: "Good, now give me TWO SP songs which are different from the rest". He: "NOOOOOOOOO!". He fell on his knees. He thought, why did he like SP? Why was he a fan of the band? The answer was: he likes to listen to the same song over and over again - with different lyrics, but the same guitars, the same drums, and the same emo-istic vocals.
M Shadows (Avenged Sevenfold vocalist) - He's GAY!!!
