I can't really say, because I dislike 90% of the bands in any given genre, including the most "definitive" bands that genre nazi's say you must love. XD Plus, most of the music I like blends different genres together.
That said, these are the genres most of the music I like LOOSELY fits into:
-Death-pop (Orgy, Marilyn Manson, Zeromancer, Rammstein, etc.--basically a combination of industrial, rock, pop, glam, and metal...)
-Symphonic "Kinda Black" Metal (well, just Dimmu Borgir and Cradle of Filth)
-Neo-Classical (Dark Sanctuary, Elend, Autumn Tears)
-Advant-Gard Metal (Sleepytime Gorilla Museum, Creature Feature, Stolen Babies, Fantomas)
-Alternative Metal (A Perfect Circle, Deftones, Mushroomhead, Slipknot)
-GothIC rock (NOT Bauhaus-style goth rock--this is a little bit like gothic metal but not hard enough to be metal, so it's called gothic rock. Examples are Evanescence, Within Temptation, H.I.M.)
-Industrial/gothic (just a little bit...NIN, Angelspit, Emilie Autumn, The Cruxshadows, Diary of Dreams, She Wants Revenge....)
-Movie and video game soundtracks
