Today goes down in history as the day I heard eleven random people, throughout the day, in different locations, singing and/or humming the catchy Martin Solveig hit, Hello (featuring Dragonette).

If you can create something catchy, you just figured out the up-down-left-right-A-start code to jump to the higher levels in the Industry. Boing!
