Also: Romeo Santos' 'Yo Tambien' hits top 10 on Hot Latin Songs.
Rising urban act J. Balvin continues his chart ascent as "Ay Vamos" becomes the second No. 1 on Latin Airplay for the Colombian singer. A 10 percent audience increase, to 10.7 million audience impressions according to Nielsen Music in the week ending Dec. 7, was enough to bump Juan Luis Guerra from his seven-week lead at the top (he falls 1-2).
"Vamos" also claims Greatest Gainer honors on Latin Rhythm Airplay, where it crowns the list for a ninth week. Balvin approaches the longest run at No. 1 in 2014 on the chart, when his own "6 AM" featuring Farruko spent 10 weeks at the top in 2014 (tied for most weeks with Wisin's "Adrenalina" featuring Jennifer Lopez and Ricky Martin). Balvin finishes the year as the No. 9 act on Billboard's year-end Top Latin Artists recap.
