Most mainstream metal is complete shite, whereas actually a lot of fairly commercial hip hop is great.
Hip hop is actually a progressive genre, whereas metal/prog-metal/death,black,etc metal is merely drawing on past influences. This isn't to say it make it inherently better or anything, but hip hop is constantly evolving and progressing with the advent of new technologies and ideas, and with the help of the never-ending innovations possible with turntabling. Trust me, I like a ton of various genres, and there is a lot of pure shit that passes for "hip hop" these days (namely anything called crunk, and most radio rap), I'm just stating the obvious that hip hop is a very progressive genre and much more so than the form of rock you'll hear today.
Who cares whether it's technically a "band" or not? Most of the great hip hop groups have been actual groups of people (Public Enemy, Wu-Tang, NWA) and a lot of more recent talents are constantly collaberating with each other as if they were in a band together. (Mos Def, Talib Kweli, Kanye, Common, Nas) Anyone who dismisses an entire GENRE of music to be terrible is an idiot. I feel inclined to do such a thing with country music, but all I know about country music is some shitty mainstream current shit and Johnny Cash (who I'm sure has some good stuff I just haven't gotten into him)... so it's pretty much the same when you all dismiss hip hop as utter crap. Hip hop, or at least electronically inclined music, seems to be the future of music, whether you or I like it or not. I'm not saying I do. I love Opeth and a ton of metal and prog bands past and present, also noise-rock like Acid Mothers Temple, Boris, etc. which all rely on traditional instruments in most songs. But I'm just trying to reveal the pure ignorance many of you (and a lot of likeminded, closeminded "METALHEADS") seem to possess.
