The song is the third No. 1 from the duo's introductory album "Here's to the Good Times."

-- Linkin Park: While Linkin Park has paired with rappers in the past for collaborative works, most famously Jay Z on "Collision Course," the band throws a curveball with its latest song, which features iconic MC Rakim. "Guilty All the Same," the lead single from the group's studio album due this summer, arrives at No. 28 the Alternative airplay chart. It's the band's milestone 25th entry on the ranking.

-- Victor Manuelle: He once again ties the record of most No. 1s on Tropical Airplay, as "Una Vez Mas," featuring Reik, vaults 8-1. Manuelle matches Marc Anthony's sum of 23 No. 1s, as both salseros have continually jockeyed for the crown in recent years. Anthony had pulled ahead in January with "Cambio De Piel."

-- Julion Alvarez y Su Norteño Banda: They attain their third Regional Mexican Airplay topper as "Te Hubieras Ido Antes" springs 6-1. The song gains by 42 percent to 9.2 million in audience.
