For me, it's Metal or Progressive. I prefer Death and Doom Metal to most other types of Metal, and I enjoy Progressive Rock.
Specifically: Doom Metal: Katatonia, Paradise Lost, My Dying Bride.
Death Metal: The Black Dahlia Murder, Death, Dark Sermon.
Progressive Rock: Porcupine Tree, Tool, A Perfect Circle.
At the moment i am very much in love with trance music. My favorite artist would be tiesto and welcome to ibiza and maximal crazy are my favorite. i listen to them every time and i just love them.
