Plus, Mariah Carey's "Infinity" debuts and Jessie J's 'Pitch Perfect 2' single arrives!

Carly Rae Jepsen springs 14-1 on Billboard + Twitter Top Tracks (dated May 16) with "I Really Like You," thanks to her latest assist from Justin Bieber, who tweeted on April 27 that the song was newly available in the U.K. and encouraged fans to create lip-sync videos inspired by the song. Bieber previously starred in his own lip-sync clip for "Really," which also boasted appearances from Ariana Grande, Lance Bass and Kendall Jenner. The celebrity-fueled clip helped push the song 26-3 on the May 2-dated chart. The track continues to perform well domestically, with 2.7 million U.S. streams in the week ending May 3, according to Nielsen Music.

. The veteran singer (and newly announced Billboard Music Awards performer) raised her social media presence for the song’s premiere, registering a 113 percent jump in Twitter mentions for the week, according to Next Big Sound. The social media push also helps “Infinity” reach 1.8 million U.S. streams for the week, according to Nielsen Music, and fuels the song’s No. 82 debut on the Billboard Hot 100.

Tori’s \'Smile\' Shines: Rising singer-songwriter Tori Kelly debuts at No. 18 with "Unbreakable Smile," the title track from her June 23 debut full-length album on Capitol Records. The Scooter Braun-managed artist bows thanks to supportive tweets from Meghan Trainor and Scott Hoying (of Pentatonix), as the song sports 495,000 streams for the week. With the entrance, Kelly instantly surpasses the No. 25 peak on the chart of her previous chart hit, "Nobody Love."
