I hate feeling like the odd man out here. It happens too much!
Personally, I'm a huge fan of melding of genres, especially those at seemingly opposite ends of the spectrum. Rap and metal/hard rock just work together. Jay-Z/Linkin Park's Collision Course album is proof of this. Even if I wouldn't call Linkin Park metal, or even really hard rock for that matter, that album was fucking brilliant. Even the songs Linkin Park has done by themselves with a rapper over the top (I can't remember the guy's name, but songs like Bleed it Out, Nobody's Listening, etc.) are awesome. The remix of Crank Dat Soulja Boy that Travis Barker just did is also fantastic.
I now feel obligated to check this album out in the hopes that it will appeal to my tastes. Then again, I also have Evanescence on my computer, so what does that really say about me?
