Renegade is a classical/electronic piece. It's mainly constructed of epic chords and a kickass bass synth :P It's still a work in progress though...
444 is a Daft Punk-y sounding song (in my opinion). It's very different from typical electronic songs. I don't know how else to describe it, so if you want to know what its like, then have a listen :)
And my entry for the Robot Day 2010 Audio Competition is The Robot Factory. It used factory sounds for the beat and high pitched beeps and bloops to make the melodies. I suggest you check it out. Its pretty awesome if I do say so myself :D
Hope you enjoy!
