You've never heard of it because it's not worth mentioning. Trust me.
Also, someone mentioned End of Ponies. Never read it (of course), but this song is pretty damn good.

I'm of the opinion that the very best of each art (JJ for drawing, her for fics, etc) are actually professionals that are secretly pretending to be normal people.
Take music for example. MandoPony was in a commercial in New England where he was singing an acoustic cover of a Beatles song. Ponyphonic's video of his cover of Winter Wrap Up clearly shows him using professional equipment.
