Wow, I feel out of place... I dislike Kanye, and have actually never heard a real beat by Dre (going to find him on youtube right now)
Here are some...
Deadmau5
Wolfgang Gartner
Owl City (yeah...awkward)
Dubmood
Gorillaz
Trans-siberian Ochestra
And 100 others... But Most influentially,
Renard Queenston (and his 20 AKA's) <=======*FREAKING GENIUS WITH LIKE A THOUSAND SONGS*
AKA: Kitsune^2, Jackal Queenston, Furries in a Blender, Mayhem, Klippa, Negaren, The quick brown fox
