It's summer!Where I come from back in The Nation's Swamp the advent of summer always meant one thing: We must determine the identity of The Summer Jam.Generally, The Summer Jam identifies its own self. Because it's blasting out of every other car window, dorm window, jukebox, iPod earbud, and cheesy reality show. Which also means usually it's some flavor of commercial R&B. Kelis or J. Timberlake
