I have a strong distaste for basing music on it's genre. Good music is good music, period. When you adopt a mindset like that... you prevent yourself from enjoying that type of music. I'm not saying that you have to like everything... but if someone is out there doing their thing and being successful, I give 'em some props for that, they deserve respect.
I tend to listen to more rock/punk rock/alternative music, but that isn't by much--my tastes are pretty spread across the board.
