Medicine men - Electric voodoo
DJ Tiesto - pretty much anything by him, he was rated one of the best DJs in the world a few years ago *saluts*
Daft Punk - Digital Love/Robot Rock/harder better faster stronger
Cosmic Gate - FireWire
Ferry Corsten - Rock Your Body Rock
Slinky - The Revenge

You could also try typing in a DJ or song you like into Pandora Internet Radio - Find New Music, Listen to Free Web Radio and it'll give you a list of songs that are similar to it. Helped me when i was looking for new songs so hopefully it should help you too. =)
