I know the instruments don't exactly sound the best... Also, some of the transitions between songs aren't that good. It was the best I could do. This is a medley filled with all my favorite MLP:FiM songs. Not all the songs are included either because they were too short, or they were too hard to rewrite, or I didn't really like it. It's been written for a string quartet + bass (2 violins, 1 viola, 1 cello, 1 bass).
Songs in order:
Main Theme
Art of the Dress
Cupcakes!
Giggle at the Ghosties
Find a Pet
Winter Wrap Up
Hush Now Quiet Now (Fluttershy, then Sweetie Belle)
Becoming Popular/The Pony Everypony should know
At the Gala
