His grand total climbs to 21 charting tracks, as he's also a featured act on four additional songs.
Drake surpasses his previous record for the most concurrently-charting songs -- 14 -- which he matched a week ago (on the chart dated Feb. 25) following the debut of his album.
The new songs enter off the strength of downloads and streaming, with every track from the set logging no less than 1.8 million U.S. streams in the week ending Feb. 22, according to Nielsen Music. Of the album's tracks, "Energy" leads the pack, taking Streaming Gainer honors and increasing by 201 percent (to 4.6 million clicks), with 82 percent stemming from Spotify plays. Sales of the cut also rise (up 21 percent to 77,000 downloads), driving it 4-1 on Rap Digital Songs -- his first No. 1 as a lead act (and fourth overall) on the still-young chart.
