I like techno, hardcore techno, electro, ambient, trance, happy hardcore, symphonic, gothic and fantasy metal, movie scores (non-movie scores), classical.
As T-Snake I have on occasion produced a variety of electronic forms of music my self, primarily, electro, techno and trance.
I like lots of old school rap/hip hop (82-92) and for the most part despise modern hip hop and it's overwhelming message of violence, drugs, homophobia, misogyny, and frankly lack of inspired sound.
Top 40 music is, in my opinion, generally for mindless people without the ability to explore more music.
I do not like "rock&roll" in general and specifically cannot stand classic rock and it's off-shoots. Whine-rock (Green Day, etc.) annoys me to death and country music artists are laughable these days.
