Me? Well I listen to a mix of genres. I listen to lots of Core music, specifically Metalcore, Deathcore, and Post-Hardcore. In layman's terms this genre is known as "screamo" though it has it's own intricacies in each style.
I like Rock in general, specifically Metal, Punk, Classic Rock, and Pop/Alternative Rock. I like and listen to a lot of Electronic/Synth based music of any type (Drum & Bass, House, Trance, Dance/DJ, Dubstep, etc.).
I like a bit of Pop and Rap/Hip-Hop, though I don't listen to those styles as much.
Surprisingly enough I also like to listen to Bluegrass and British/Irish folk songs (groups like Great Big Sea).
And I have never found a pony song I didn't like. My favorites are Rainbow Factory
, Dashstep, DJ Pon-3 House Mix, and Rainbow Dash's You're Gonna Go Far Kid (the song is a real song by the band The Offspring, but's been slightly sped up).
