Techno... is not good. I don't like the fast, unorganized beats. It's all random, and repetive. If you want some good music that is electronic and awesome to listen to, listen to Acid, Ambient, Synthpop, Futurepop, House, and Industrial (if you like hard rock). Those are some good electronic music genres.

Acid/Ambient = Aphex Twin, The Orb
Synthpop = Apoptygma Berzerk, Sexcopter Rul, Toxic Coma
Futurepop = VNV Nation, Velvet Acid Christ
House = Daft Punk
Industrial = Skinny Puppy, KMFDM, Nine Inch Nails
