I think if I had to go by what I listen to the most, it would be more trance or ambient electronic music, since I listen to that while I'm working or sleeping often, but I also like just about everything, from bluegrass/newgrass, to hip-hop, to rock, to classical and show tunes. The more music I hear, the more music I like, for the most part.
I work for a multi continental company in a very professional atmosphere and I have tattoos, piercings, fantasy coloured hair, and part of my head shaved. How you look has zero effect on your ability to do your job!
