When I used the preview video, I was afraid that this was like some other accounts, and that the music might be some sort of AI-made-not-even-finished-stuff.
Boy was I wrong.
I'm glad I downloaded the music pack.
These are all very good.
All of these managed to be proper background music that would allow you to focus on dialogue, if present, while still being pleasant enough to enjoy all on its own.
The only thing I can think to add is this:
In a game, music often has to loop. JShaw did this, and you might be able to do it, too: Give us a chart for timestamps for "perfect looping" so we can add it to our projects without editing your mp3 files. (Like, each track gets a line for "at time 2:34:301, loop back to 0:22:204")
So in case it wasn't clear, 5/5!
