Worst Song Ever?

Rebecca Black's "Friday": Worst Song Ever - Watch more Funny Videos

Is this truly the worst song ever? It is terrible, but is it any worse than any number of bubble gum songs of the 70s, most of disco, and much of the lame in hip hop. My milkshakes, for example, is lame. C'mon. It's lame. So is "Good Morning Starshine, the earth says hello." Particularly the chorus.

I admit, autotune takes this to a hole noder lebel of lame.
