It doesn't matter what genre the Dave Matthews Band is, since they just aren't good. I'd like to see anyone explain to me why I'm wrong, too.
I was oversaturated with bands like DMB and Jack Johnson when I was in high school. That's all I fucking heard and I hated it. It's yuppie crap. Luckily, I don't hear it much anymore, but I still really hate it.
Jack Johnson is such an overrated singer-songwriter. Elliott Smith is much better.
I could not stand 99% of brutal death metal for a while. I like about 30% now.
If your a drummer, or appreciate any type of musicianship outside of the metal realm, then maybe you would understand. But I know why people hate bands like that, because they are happy and popular. Once you pull your head out of your ass and grow up, you learn to respect many different musical artists.
.I hated Cannibal Corpse once, Tomb of the Mutilated in particular cause I thought the growls were crappy and didn't sound good, but strangely, now I love the growls.
