I appreciate fine pony art and music that has been made by the Brony community, see, we DO have talent... Luna is best alicorn, I also run the "Bronies of Moddb" group.
The final version of I Will Rise, i've been a bit slow to upload this, but it's good, though you have to buy the whole album to get it...
why do we take things ment for little girls and make it epic
Not sure, because of the topic perhaps.
The fandom has a unique ability to portray such emotion into even the simplest things, like this scenario for example of Trixie running away, fandom made the story of her return and what happens after that, though it is never mentioned in the show what happens to her WE made our own idea.
And this song tells of her return and eventual showdown with Twilight, who upstaged her in the show, she come's back to take her place as the most powerful unicorn in all of Equestria!
