The Billboard Hot 100:
As previously reported, Train's "Drive By" chugs into the Billboard Hot 100's top 10 in its 18th week, marking the longest ascent to the top 10 this year, while Gotye's "Somebody That I Used to Know" (featuring Kimbra) spends a fifth week at No. 1. Let's see who else keeps on rolling -- or gets derailed -- on this week's chart.
-- Jennifer Lopez: The singer logs her fourth top 10 with "Dance Again" (featuring Pitbull) on Hot Digital Songs, where the track bounds 15-9 (104,000 downloads sold, up 39%, according to Nielsen SoundScan). On the Hot 100, it climbs to a new peak with Digital Gainer honors (20-17).
-- LMFAO: Party on, for a 60th week. The duo's "Party Rock Anthem" (featuring Lauren Bennett and GoonRock), which holds at No. 44, becomes just the ninth title to remain on the Hot 100 for at least 60 weeks. It ties Los Del Rio's "Macarena" (1995-96) for the longest stay for a song by a duo.
-- 2Chainz: The rapper formerly known as Tity Boi debuts at No. 45 on the Hot 100 with "No Lie," featuring Drake (93,000 downloads sold). The track previews 2Chainz's debut studio effort, Based on a T.R.U. Story, due Aug. 14. Chris Brown, Lil Wayne, Ludacris, Rick Ross and Kanye West are also set to appear on the album.
-- Justin Bieber: "Turn to You (Mother's Day Dedication)," the teen star's heartfelt ode to his mother, Pattie Mallette, debuts at No. 60 on the Hot 100. The track sold 79,000, with all proceeds benefitting single mothers in need. The ballad is not set to be included on his third studio album, Believe, due June 19.
-- B.o.B: After benefitting from the release of his second album, Strange Clouds, last week, the rapper's "Both of Us," with country titan Taylor Swift, plummets 18-75 in its second week on the Hot 100. It falls 8-36 on Hot Digital Songs with a 65% decrease to 50,000.
