One use-case that immediately jumped to mind for an API plugin is integration with popular games for game streamers to use. Something that detects that you're in the middle of a gunfight vs just chilling in the lobby, and selects/modifies the music appropriately.
Some video games do this automatically with their in-game music, but not all, and many streamers prefer using other music to avoid it getting stale.
