The last printed chart of 2015 will have Def Jam’s Alessia Cara hold at #1 with "Here," while Post Malone's “White Iverson” (Republic) stays posted right behind her. The Top 5 is loaded with big gainers, as Travi$ Scott's “Antidote” (Grand Hustle/Epic), Justin Bieber's “Sorry” (RBMG/Def Jam) and Columbia's Dej Loaf all pick up major steam. Who will be #1 Jan 4th? Adding to the mystery is the fact that Drake & Future's “Jumpman” (YMCMB/A1/Epic/Republic) and The Weeknd's “In The Night” (XO) are cruising upwards. Meanwhile, The Chainsmokers' “Roses” (Disruptor/Columbia) makes a big jump on the chart, as does Yo Gotti's “Down In The DM” (Epic). Look for Adrian Marcel's “Take Your Time” (L7), Jason Derulo's “Get Ugly” (BH/Warner Bros.) and Chris Brown's “Back To Sleep” (RCA) to debut this week.
