Atlas Genius's pulsating, electro-fueled new single, "Molecules" (Warner Bros.), is the Most Added record this week. A real story is building around Robert DeLong's "Don't Wait Up," which had a real strong day of adds for Glassnote. RCA's Walk The Moon closes out more stations with "Different Colors," while Columbia continues to impress with Coleman Hell's "2 Heads." Dan Auerbach from Black Keys fame has a side project titled Arcs (Nonesuch/Warner Bros,) and it already has early action on the first single, "Outta My Mind." Other winners included AWOLNATION's "I Am" (Red Bull) and "West End Kids" by New Politics (Crush/Warner Bros.)
