HetaOni Music

I’ve searched but didn’t find ANYTHING about HetaOni on this forum, which really surprises me.
No one around here ever heard of it? XD" But I digress.
The reason for this topic is obviously, because I’m looking for the music used in HetaOni.
A lot of tracks are uploaded on YouTube, but I was wondering if someone had something like a zip-file of all the tracks used so far?

Actually, I found a zip-file myself already, but the quality of the tracks varies greatly! Some have in-game soundeffects mixed into them, others are extremly loud or pretty quiet, and so on…

And of course, I’d like to know the original titles or composers of the tracks, because most of them are named after the scences they played in.

Yeah, that’s it, I guess… Hope someone can help me out here ^^"
