First off we have a PMV to the really neat Proud to be a Brony song, followed by one of the most professional video explanations of FiM I have seen so far (something I'd probably show people instead of explaining it myself tbh.)
And finishing off with a really neat song that I can't really figure out a category for. If it's dubstep, then I guess I have finally been converted.
1.) Proud to Be a Brony
2.) Something's WRONG with MY LITTLE PONY Friendship is magic
3.) Rainbow Factory
