The funky theme from Zaxxon's Motherbase 2000, as seen in Idol Round 5. This hasn't really been recieved that well in Idol, but honestly the main problem when I submitted this to it seemed to be about the song choice, and rarely about the port itself, so I think this should be fine to submit.
Anyway, I'd say this should fit urban, night and space zones quite well, but honestly I'm not too sure myself. Just use this in a way you feel comfortable I guess lol
EDIT: Added a optimized and a unoptimized version; use the optimized version if you want to insert this into a hack, because it removes a lot of the space this would have (tho it doesn't change much of the song); the unoptimized version is just for listening lol
