Answer by  echollie (7)

It is the title of a song by Pink Floyd. The song begins, "Remember when you were young, you shone like the sun, shine on you crazy diamond", a wistful look toward one's youth, a reminder of what once was in the face of older age, bitterness, and disillusionment.

Shine On You Crazy Diamond was a song by Pink Floyd off the Wish You Were Here album. It's a song that was written about one of the band member's brothers. Basically it means keep shining, keep being you, you're special.
