Kenny and Mark remain on the dance floor with Madonna (Timberlake and Timbaland) for a simmering song about moving your body.  Topics include thick beats, smoking grass, Madonna as professor, musical courtships, the weirdness of star billing, NPR’s Tiny Desk series, the virtues of being beautiful or interesting, Janet Jackson’s Discipline, apocalyptic chaos, Justin’s voice, artistic flexing, and who’s exactly taking WHO to the club.  Plus a discussion on the shift in focus from classic songwriting structure to production that epitomizes the sound (and culture) of the late 2000s.  Do you wanna take it further?
