Hey, sorry had a busy day with the holiday yesterday.
This is the best place to look: https://www.joegarofalomusic.com/music
First item is a reel specifically for upbeat/battle music, and then there are a few other projects, 48 hour film, music from a previous game jam entry, and some other stuff. As far as implementation, I have just begun learning FMOD, so I would be able to pop things in there and do some simple things like creating conditions, tying music cues to parameters, etc.
