I feel bad that everyone offers me help and advice and I’m still a noob at blender so…
I’ll ask…do you ever wish you could add an original soundtrack to your game without stressing about copyrights? Here’s one solution: Go to where you can download the latest express version of ACID. It’s very good looping software for the novice musician. Bonus: Every week AcidPlanet offers an 8Pack of loops, ROYALTY FREE, for mixing. The material is a wide range of techno, Urban, HipHop, Industrial, Metal (perfect for creating atmosphere.) Acid is very usesr friendly. You can scroll tracks, move tracks change bps for a track and even record your own loops (need wave editor to render track, not recomended for the novice) ACID PRO itself costs a few hundred dollars but the biggest difference in the express version is that it doesn’t come equipped with a wave editor, and it only has the capability of editing 10 tracks per project (which I’ve found is enough, unless you’re a musician.)
Check it out and let me know how it works out.
P.S. You can also purchase loop libraries (those are "public domain"as well.) but after collecting loops for a few months you should have plenty of material to work with.
