A music rush

This is a short story on how everyone's favorite DJ pony got her cutie mark. Inspired by a small scene I saw in the Official MLP comic #11.
A few weeks after Vinyl arrives at Canterlot with her family, she meets Octavia Melody and a few other friendly faces in the city. A love for music runs in her family but she still hasn't found her special talent. That changes one faithful day at the parade of the year.
