The same as Majek, with emoish hardcore being my favourite. I like the original HC a lot, too. The swedish stuff is just awesome, Refused in particular. I like electronic music too, mainly trip-hop, downtempo, jungle and anything with experimental on it. Mainly Soundmurderer, Aphex Twin, Squarepusher, Portishead and various other DJ's from the electronics side, and Taking Back Sunday, Thursday, Sunny Day Real Estate, Bright Eyes, Iron and Wine, Suicidal Tendencies and the Mike Ness solos, The Shins ( i love that band) and Flake Music from the Indie/punk side. Ragga and all the other jamaican stuff are close to my heart, too.
edit: forgot like twenty bands from the list, but i think you get the idea
