I'm currently working on a game (which is why I've uploaded even less than usual, if you're wondering)... I can handle coding and graphics on my own, but something I'm not good at is music. I have trouble finding what I want, so now I'm asking: Do any of you know of any good melody or artist that I can try out? If possible, please get music from sites like Newgrounds, so I can ask the composer for permission and not use copyrighted music.

The scenes and environments that I currently need music for are:
Stages:
City streets (initial stage)
Scrapyard/robotic graveyard (it's got robo-zombies, after all)
Acid wastes (treatment plant?)
Arena
Playground/tivoli
Radio tower
Base (fake last stage?)
Hi-tech base (last stage)
Boss fight

Other music:
Save/load screen
Main screen
City/police station (when you run around without being on a stage)
Ending music

... and whatever else you may think of. The setting is future hi-tech, kind of Megaman-styled, and as such you play as a robot. Any help is appreciated!
