Pokemon SV: Team Star Grunt Battle

It only plays in like seven battles in the game, which is more than once, but they're some of the shortest battles in the game and they aren't replayable. The trainers with this music are all dorks and each has one pokemon and many players will take it out well before they hear the whole song, which is a banger and honestly way better than the Team Star boss battle music.
