The best genre of music is the genre that involves music... in other words, there really isn't one, in my opinion. Music itself is just amazing and the world wouldn't be the same without, no matter what style it is. Personally, I'm not into that much classic rock, even though I'm in a band. I also don't like Metallica and I'm in a metal band... ZOMG! With that being said though, I recognize their talent and what they have done for music, and not just Metallica but classic rock in general, because without them my band wouldn't be here.
But hey! If you like like bands like August Burns Red and what not, check out my band!
