Music History Morsel

From an article by Steve Sailer:

The Sugarhill Gang’s lyrics might sound dorky now—“Me, my crew, and my friends are gonna try to move your feet”—but the group actually coined the line, “Throw your hands up in the air, and wave them around like you just don’t care,” which has been repeated ad nauseam by hip-hop artists for the past three decades.

I wasn't aware of that, but it's right there in their 1979 hit "Rapper's Delight". The article also contains an explanation of stagnation in pop music. A post of mine about innovation in the arts is here.
