The Greatest Gainer of the Week will be Republic's Lorde with her newly-released single "Green Light," which is extra significant because it's happening prior to the official impact date of 3/6. Look for this song to not only to be Most Added next week, but to chart well inside the Top 30. Another track experiencing good spin gains this week is The Chainsmokers & Coldplay's "Something Just Like This" (Disruptor/Columbia), which also charts in a week and lands Top 30. Other songs with notable momentum include Linkin Park f/Kiiara's "Heavy" (Warner Bros.) launching up to #24 and Marian Hill's "Down" moving up to #14 (Photo Finish/Republic).
