Plus, LANCO returns to No. 1 and Brooke Simpson from "The Voice" debuts at No. 5.
One Direction member Louis Tomlinson vaults 24-2 on Billboard's Emerging Artist chart (dated Dec. 23), matching his Sept. 9 peak.
Sparking the surge: the release of his fourth solo track "Miss You." The song drew 1.8 million streams and sold 19,000 downloads in its opening week, according to Nielsen Music, and enters Digital Song Sales at No. 15.
The Emerging Artists chart uses the same formula as the all-encompassing Billboard Artist 100, which measures activity across multiple Billboard charts, including the Billboard Hot 100, Billboard 200 and the Social 50. However, the Emerging Artists chart excludes acts that have notched a top 25 entry on either the Hot 100 or Billboard 200, as well as artists that have achieved two or more top 10s on Billboard's "Hot" song genre charts and/or consumption-based "Top" album genre rankings.
