Why can't I find the song "Light Up The Dark" on itunes?

Well, numero uno! It's not on his album, and all songs from his album are there. Numero dos! He doesn't have it listed as an actual song, like it's not a single, it's just a song he recorded that got out on the internet that nobody decided to take down because the majority of people liked it and they just couldn't be bothered to make it completely official. I hoped that help somewhat... here's a random picture of him!(= Inn't his face just adorable?!<3
