Well, obviously I have a bit of a crossover into Rock territory. Pink Floyd, System Of A Down, Guns And Roses, Scorpions, KISS etc etc.
A tiny bit of punk, Dead Kennedys and MSI mainly.
Apart from that, I really do listen to almost nothing else, voluntarily anyway. Honestly, I just don't like anything else. What can I say, it's not who I am.
Oh, also classical can always be good.
I think it's because I like "complex" music. I'm aware Rock has some talented bands (I listen to a lot of them), as does pretty much every genre. Maybe I just don't like the style either. There is one Pop singer I don't mind, I forget her name, but she's actually an incredible guitarist. Her vocals and lyrics and everything else is as generic as most Pop, but the guitar is actually really good...
