I love electronic dance music: Dub Step, Electro, Progressive & Tech House. I DJ as well so I listen to that music all day every day, finding new music, listening to other DJ's mixes, trying new music whenever I spin. I look for songs that aren't too repetitive, which mind you is insanely difficult in this genre. If it's Electro, Tech House or Dub Step I look for bass lines, dirty and pumping. Progressive is more about melody, and I really love female vocals too. Here are some examples of some of my all time favorite tracks.
Deadmau5 - Paco Di Bango's World
Wolfgang Gartner - Clap
Deadmau5 - I Remember
Deadmau5 - Not Exactly
Joris Voorn - The Secret
Claude Von Stroke - Vocal Chords
16Bit vs Yael Naim "Toxic [16 Bit Remix]"
