Finally took the time to figure out how track queries work. Still have a bit to figure out, and I don't know how to write a query script to generate a reply. But this is the end result in hopes someone can do something useful. All comments are denoted with //

I don't have the time to write the script for it anytime soon, but this is all the information needed to fix the track query function so ya'll can easily download tracks. If someone does take the time for fixing it, I can provide the hosting if needed for it.

Code:
