Power Couple: Zedd and Selena Gomez's first collective effort yields a rich result: The pair debuts at No. 1 on Billboard + Twitter Top Tracks with "I Want You to Know." The rumored couple blasts in at the top thanks to "Know" notching 2.3 million U.S. streams for the week ending March 1, according to Nielsen Music. With the debut, Gomez earns her first No. 1 on the eight-month-old survey, besting the No. 2 peak of "The Heart Wants What It Wants" in November 2014. Zedd, meanwhile, scores his second leader, following "Break Free," his collaboration with Ariana Grande, which topped the tally last August. "Know" also reaches the Billboard Hot 100, where it snags a No. 17 debut.

Jack U's Double Play: As Skrillex and Diplo's collaborative album -- Skrillex & Diplo Present Jack U -- arrives at No. 1 on Top Dance/Electronic Albums, the DJ team earns two debuts on the latest Top Tracks tally. At No. 4, the album's "Where Are U Now," featuring Justin Bieber enters, followed by a No. 23 start for "To U," featuring British duo AlunaGeorge. The Bieber track has collected more than 1.4 million global views on YouTube since its premiere on Feb. 27, and also bows at No. 4 on Dance/Electronic Digital Songs (20,000 sold for the week).

Sheeran Gets "Dirrty": Ed Sheeran also boasts a double debut on Top Tracks with two cover tunes from his Feb. 24 performance on Radio 1's Live Lounge. The singer-songwriter tackled Christina Aguilera's "Dirrty" and O.T. Genasis' "Coco," and his renditions arrive at No. 22 and No. 31, respectively. The covers help Sheeran earn a trifecta of titles on this week's survey: his current single "Thinking Out Loud" slides 4-5 in its twenty-eighth week on the chart.

"Glory"-fied Oscars: After winning best original song during the Feb. 22 Academy Awards, Common and John Legend's "Glory" rallies to a No. 2 re-entry on Billboard + Twitter Top Tracks. The Oscar triumph, along with Common & Legend's performance during the telecast, spurred the song to more than 1.5 million streams and more than 67,000 in sales units for the week ending Mar. 1, according to Nielsen Music. In addition to its Oscar success, "Glory" earns its highest peak to date on Top Tracks: the song previously reached a high of No. 9 for the week ending Jan. 31. The Oscar fortune lifts "Glory" on other charts, leading to new peaks on both the Hot 100 (99-49) and Hot R&B/Hip-Hop Songs (36-18).
