Sazex, Electro or Progressive House is pretty much built on FX and beat-lines, which means; All you need is a large amount of effects, a beat which changes now and then and to spice it all up: A neat bassline/melody. However, neither of those are really that important since it's a genre made for mixing and live-performance - not "listen at home" material.
Q2; I tried, it went meh and I didn't like it. I might try again later though but for now I'm just doing what I can to get my music (the real stuff, not my vid-game crap) out there for recognition and live-plays. A task easier said than done!
