What I've found I liked most recently is electronic industrial. Basically, it's like metal and electronica mixed into one style. I haven't found too much music in that genre, but here's what converted me:
Artist: Theatre of Tragedy
1st song: Automatic Lover
They're a goth metal group who's started experimenting with electronica in their music. Oh man, hearing that hard revving guitar and electronic sounds adding effect, not to mention the dark flavor due to their goth background. shweeeeeeeet... btw, it's a chick singer. Gotta love that.
