I hate Fallout Boy, but I can't have "Sugar We're Going Down". I don't know why. It's so damn catchy it makes me want to die because I know I should hate it, lol.
I also hate Nirvana, but some of their songs are so-so. Nothing I listen to, though.
Bands I really hate?
Killswitch Engage. Worst cover of "Holy Diver" ever.
The Beatles. Not necessarily terrible, just terribly overrated enough to make me want to destroy them. I don't like any of their recordings at all because I hate their voices. I enjoy Aerosmith's version of "Come Together" and a few covers from Across The Universe ("Hey Jude" was beautiful), but that's it.
Red Hot Chili Peppers. Yuck. I remember when I was younger and "Californiacation" played constantly on MTV. Worst experience of my life.
Mindless Self-Indulgence, if anyone actually considers them a band.
