A snag in the MLP:ANG movie? · 2:07pm Sep 29th, 2021
The song that is playing in the unicorn's dance contest is obviously a recording because there is no live band playing it, so we can rule out it being a "heartsong" (where a character spontaneously breaks out into a song that fits the current scene). Clips are played during the contest, and then the whole song plays during the credits.
