Does anyone know a good place to get background music that can loop, i've noticed all my games are silent.

Has all kinds of sound effects, ambient noise, synthesized music, etc. You'd just have to search for it, and as far as looping goes, you may need to find a decent sound editor to do that (reccomend CoolEdit Pro - bought out by Adobe and now they call it something else). If you do use anything from this site, be sure to credit the creator (per licensing agreement for royalty-free sounds)
