Some song contest (Eurovision) had gotten so big it was a galactic event. The sponsoring company had invaded one of the planets, stolen their resources (a honey flavored flower) to make a what I think was a cereal, then set fire to the planet to destroy the farms so no one else could get access to the resource.

The singing competition then banned residents of the planet from entering the competition so they didn't have a galactic stage to speak about the sponsors shitty actions.
