do you think you could be defined by the music you listen to?

No.

I'll explain after I list the genres I do listen to:

-Trance
-Techno
-Heavy Metal
-Hard Rock
-Electronica
-Korean Pop
-Korean Rock
-Japanese Pop
-Japanese Rock

So you might say, oh, well, this particular person probably wears lots of band shirts, and can be pretty destructive because he listens to metal! -buzzer- Eh. Wrong. I have a couple band shirts, and I'm far from destructive (unless I get seriously pissed off). People would never know I listened to Metal unless I told them, because they just don't expect it, period. It's due to my 'ha-ha' and child-like personality, it completely shocks people. But because I'm Asian, they'd expect me to listen to J/K-Pop/Rock.
