It is ironic to see someone named after a NIN album complain about rap. Isn't NIN just some sad guy screamsinging bad rap?
More importantly, if you don't understand why a form of music exists, than you probably don't understand why any music exists. If you don't take the time to understand something, then of course it is all gonna be the same to you- you don't know shit about it. All metal sounds the same if you don't care enough to figure out the difference. So does country, or gospel, or folk for that matter. The only difference between NIN and staind is that trent hates life all by himself, while Staind hates life as a team, right.
