The Billboard Hot 100:
As previously reported, Gotye tops the Billboard Hot 100 as his debut entry "Somebody That I Used to Know" (featuring Kimbra) lifts 2-1, and the "Glee" cast notches its record-extending milestone 200th Hot 100.
Here's what else you need to know about this week's chart:
-- Kanye West, Big Sean, Pusha T and 2 Chainz: The rappers zoom 38-21 in their second chart week with "Mercy." The track, from the upcoming G.O.O.D. Music compilation album, rises 15-9 on Hot Digital Songs, improving by 32% to 154,000 downloads sold, according to Nielsen SoundScan. Airplay adds to the song's surge, as it soars 49-33 in its second week on Hot R&B/Hip-Hop Songs with a 49% gain in audience to eight million, according to Nielsen BDS.
-- Jennifer Lopez, Pitbull: Unlike "Mercy," the pair's "Dance Again" can't maintain its overall second-week momentum. After debuting on the Hot 100 last week at No. 27 with 118,000 downloads sold following the premiere of its video on "American Idol" (April 5), the song dips to No. 34. Following its splashy debut, the tracks' digital sales fall by 28% to 85,000, a slide that the song's early airplay can't yet offset. Still, radio is warming to the song, as it climbs 59-52 on Hot 100 Airplay with 27 million all-format audience impressions (up 33%).
-- Jason Mraz: For the first time since Jan. 28 -- its second chart week following its No. 8 debut -- "I Won't Give Up" ranks in the chart's top half (57-49). As anticipation builds for his fourth studio set, "Love Is a Four Letter Word," which could bow atop next week's Billboard 200, per industry sources, the set's lead single, "I Won't Give Up," rises 45-32 on Hot Digital Songs (59,000, up 16%). Radio helps, too: in its 13th week, the song reaches the top 10 (11-10) on Adult Top 40.
-- Kenny Chesney, Tim McGraw: Like Lopez's new single, a decline after a fast sales start outweighs budding radio growth for the stars' "Feel Like a Rock Star," which falls 40-58 in its second week. The song plummets 19-49 on Hot Digital Songs (44,000, down 52%) while lifting 62-54 on Hot 100 Airplay (24 million, up 32%). Last week, "Rock Star" made its chart arrival after Chesney and McGraw premiered the song on CBS' April 1 telecast of the 47th Annual Academy of Country Music Awards in Las Vegas.
-- Juliet Simms: The second contestant of this season's NBC reality competition "The Voice" to chart on the Hot 100 debuts at No. 86 with her version of the Police's classic "Roxanne," as performed on the show's April 9 episode. Fellow contestant Lindsey Pavao made two Hot 100 appearances earlier this year. With 45,000 downloads sold, "Roxanne" boasts the highest sum of any of the contest's hopefuls this year.
