If you haven't heard this song yet, might as well get it over with now -- you'll be hearing it every hour for the rest of the summer, year, or maybe forever. It's called "F**K YOU" or "FU" & it's by CeeLo Green, one of the guys behind Gnarls Barkley of "Crazy" fame. Insanely catchy. (And might not be safe for work.) Ex-RealNetworks CEO Rob Glaser, tweeted, "This will be the anthem of 2010. You heard it here first."
