couldn't have said it better! there are few people that are considered "great singers" that i like. i like voices that are "true" and have some kind of rawness to them. voices that are distinctive. early bob dylan, joe strummer, mark knopfler, john fogerty, phil ochs, jesse michaels... or to mention a female singer as well: patti smith.
that's why i pretty much dislike billie joes attempt to sing "clean" on the trilogy...
you know whats the worst? all those shitty pop pseudo punk bands whos singers all sound the same: high, terrible american, whiny voices... urgh. simple plan, all time low and so on...
