Update: 8/22/11 Did you enjoy this? Perhaps you'd enjoy the mash up of the Schmoyoho songs? Here's a link to my pony video with the song by Davedays. (Note; There is a link to Davedays' video in the description, go check it out if you haven't already! )

Description of the video goes here. Yep. I doubt anyone is going to read it though.
I know that there have been Rainbow Dash Double Rainbow videos before, but those were the autotuned ones.

Being the creative, not really, person I am, I used Horizon's cover. They're a pretty awesome band if you enjoy the same genre of music that I do.

Show; My Little Pony Friendship is Magic.
Song; Double Rainbow ( Cover ) by Horizons.

Here's a link to the lyrics for the video: http://www.youtube.com/watch?v=y3hJhVvGP7k&feature=feedlik
