This song was completely inspired by the picture shown (drawn by =Shibe-inu). 
Check out the original picture here: http://shibe-inu.deviantart.com/art/Scootaloo-went-a-bit-too-hardcore-301981424

Basically, this is the concept of Scootaloo becoming so depressed at being unable to fly she simply decides to jump and hope for the best. That's why the song changes from sad to happier in certain parts. Its split between the two scenarios of her succeeding or failing.
