I have too many to list, I could go on for days.
So I'll do some genres and the usual suspects.
1. Butt Rock
Laz called it Cheese Metal, whatever you want to call it, it's the worst abomination in the history of recorded music, no questions asked.
2. Hip Hop
I'm not talking about rap here, I'm not talking about R&B singers who can actually sing or perform. I'm talking about this as the new pop music, should be pretty self explanatory to Americans.
Just awful talentless hacks feigning creativity.
3. R&B since about 1995
Okay, now I'm talking about R&B. I couldn't name two artists who premeired after 1995 I have any respect for. I don't what else to say here, it's just like hip-hop with slightly more talent and just as much lack of creativity.
4. Emo-Punk, what the fuck ever it's called
Blink 182 and that crowd, just atrocious. They wouldn't know punk if it bit them on the ass, fuck em all.
5. Southern Rock
Nasty, Lynyrd Skynyrd and the whole gang, just uninspired bubba rock.
6. 70's Arena cock rock
Kiss is the poster child, Boston and countless others, REO, Styx fucking abominations.
7. Post Grunge
Would be higher but they were apeing some great bands, so there was some residual decency. Other than that, I hope they all crash like Poison did. Creed, Godsmack, fuck you know who they are and there are tons of them.
8. Post Post Grunge
Seether, Nickelback. Pretty much the hard rock of TODAY. Awful.
9. Nu-Metal (The rap faction)
Korn, Limp Bizkit, the list could go on and on. A few decent bands (Deftones and maybe they shouldn't be in this genre) but mostly it took a brilliant sound pioneered by Faith No More and Rage Against The Machine (amongst others) and bastardized it. Lame as can be.
10. Almost all Country since about 1990
the Garth Brooks big hat and pretty shirt syndrome. It all sucks.
