Song name: The New
I thought "The New" would fit this song nicely, because it feels like it's a new theme with a different catch to it. Also, since you're using it w/ GarageBand it sounds like more of an Industrial House beat than a DnB (the latter's faster and a hell of a lot more aggro in terms of style and tempo).
This is pretty good for a loop or just an experimental beat. My complaint is whether you can extend the ideas and make it longer and meaner (not mean as in worse, but in terms of continuing the energy for longer, sicker, phases, more melodies, a possible smooth bassline for the tune to ride on, etc.).
