Pop songs should be happy, and proliferating like liberated little algae. Are we all hanging on Usher’s abs? Chris Martin’s stubble? Dwayne Carter’s, um, chains? The Jonas Brothers? (Why did we take Hanson for granted?) Where is the song that can slow down time and make us like the fact that Top 40 plays the same hits over and over?It's my opinion that "Clumsy" by Fergie, had it not been released way back in September of 2007, would have been that perfect breezy summer hit. I only discovered it a few months ago (terrific video!) and it's hardly left my mind's library of hummable tunes since.
