This shouldn't have happened. But it did, and it's amazing.
If you had asked us what we thought a piano version of the Nyan Cat theme played at the same time as Rebecca Black's "Friday" would sound like, we might have said, "What do you think a chainsaw attack and a child dying of cholera" sound like? But we would have been wrong. These two tunes, insufferable individually, actually make beautiful music together.
Of course, all credit goes to Lara, that Australian piano-meme-playing wunderkind.
