I won't say "I hate rap or hip-hop" but it's a genre of music I struggle to get into as a person. The ability to "rhyme" isn't a point which automatically sells me on music and I can't say the "social issues" invovled with it are that engaging to me as a person. Everyone always says "you have to listen to the message...". What if I just want artistic, soothing, dark, beautiful elegance in my music? Then again I am one of the most anti-sociological people you can meet. I dislike Rage Against the Machien solely because of their lyrical content. They are competent as musicians overall, but they always tried to appeal to "those kids" who never knew that much about politics outside of their Che T-shirts.
The same can be said for "Indie Rock". It feels to me like it's trying to repeat the artistic nature of the 1970's by doing it in this psuedo, wannabee, shallow way that gives the 1990's bands (REM, Radiohead, Oasis, Smashing Pumpkins) a run for their money. Very few of these bands have anything fun to say, musical depth, or otherwise. Just a broad category for otherwise "random bands" that just fall into the definition of not having enough talent to make it anywhere are meant for bars around college towns.
To all those who can't get into metal...I will just simply state that it has depth unobservable to those who choose not to challenge themselves as music listeners. Once you go past the "growling isn't singing stage" you have found the true, hidden, bastard child of the Beatles, Bob Dylan, and Hendrix's legacy.
