This is a package that contains a dynamic FMOD track (and all parent/support files) of music that is light electro and tense but not dramatic in nature.
You can plug FMOD into Unity very easily and edit/implement in real time. Check this video out for further information.

If you want to use Unity's audio tools instead, you can go into the assets folder and you'll find the two high quality wav files, and switch between them using Unity's faders.
