The Dillinger Escape Plan for real screaming ;)
it's just a matter of opinion, t.b.h. I like some bands with growling and some with clean vocals, mostly I don't like screaming with high voices and such, sometimes I think bands are better off with clean singing and other with growling
it's not about whether or not they're good singers, it's their style to sing and yeah, some really can trash a nice song with it
personally for example, I dislike Emo, sometimes nice music and then some kid comes whining along, I love Dream Theater, Blind Guardian, In Flames, Michael Jackson and Frank Sinatra though :p
= good music is good drinking =
