My little pony-Equestria girls: Taming of the sirens

The characters include Aria, Sotana, Adiago, Twilight and her friends.

After a Deja vu-type battle of the bands-rematch, the sirens girls are no longer tone-deaf, but they've gained the power of good singing. Right towards the end, when Poseidon, a large male siren comes and asks his daughters to forgive him, Pinkie pie says "hey, do you know what this calls for? A party!"

Adiago sings with her new friends, in the karaoke party. Then, the Dazzlings write a letter to Crystal Prep's Principal Cadence
