I recently got the idea to make a PMV after hearing this song again and realizing how well it fit Friendship is Magic.

Halfway through making it I decided it would be really fun to include a clip from every episode of Season 1, and now that I've done so, I think I'll do the same for Season 2 once it is all wrapped up next year.

UPDATE 8/8/11 - Thanks for the feature, EquestriaDaily!
