I'd say that's the most epic enhancement of Rainbow Dash's already awesome At The Gala part we have seen so far in the first slot. It's got some rap, some great singing, and all flows together really well.
We also have some Today, the song that premiered at EFNW, and a parody of Plain White T. Check them out below!
1.) VINXIS & MC Flowny feat. Feather ~Dream~ (Been Dreaming Remix)
2.) Today (feat. Metajoker) - Michael A. + ArtAttack VIP
3.) Dear Twilight Sparkle-MLP FIM- Plain White T's Parody
