Anybody said John Mayer and the "singers" from Suicide Silence and WhiteChapel. Two epicly inferior bands- as most deathcore is

I'm a bad singer. Awful. Just plain terrible.

I like these two guys, but I'm aware neither one of them can sing.

Trey Anastasio
Bob Dylan

Trey Anastasio, unfortunately, doesn't seem aware at this point in his career that he can't sing, and that's kind of strange.

Bob Dylan probably knows.

That goes without saying.

i know, i thought i'd just throw it out there anyway

Justin Bieber... why, oh why are we afflicted with such dross...

Justin Bieber can totally sing. He's just the most boring person on the planet.

Randy Newman, Stephen Malkmus, Mark E Smith, Donald ***en, Frank Black Francis, John Darnielle.
To quote Silver Jews' frontman and presiding genius David Berman, "All my favourite singers can't sing"

He's... like... 14

Haha, I don't have ten but the only one that comes to mind with a legitimate band and reputation is Les Claypool. Those bass riffs totally make up for some of the terrible vocs he does though.
