¡MAYDAY!

Affiliated with Tech N9ne's Strange Music label, the hip-hop group Mayday!'s 2006 national hit, "Groundhog Day," did not start out having any rotation on radio or MTV, but rather on YouTube. The DJ Craze-produced ode to the office nine-to-fiver, with Cee-Lo Green on the hook in Gnarls Barkley mode, received over two million views within just 48 hours, breaking the site's record. The story broke out on many mainstream media outlets (including ABC's World News Tonight and The New York Times), stirring up interest from some major record labels.
