After weeks of largely less than stellar numbers, Latin music sales experienced an upswing, buoyed by last month's Billboard Latin Music Awards and Mother's Day (May 8) -- typically a major music retail holiday.

While the immediate impact of the Billboard Latin Music Awards -- which aired live April 28 on the Telemundo Network -- wasn't major, a week later, those who performed saw an emphatic sales boost.

Most benefited was Cristian Castro, with sales of "Viva el Principe." His homage to Mexican crooner José José almost doubling to place him at No. 2 on Billboard's Top Latin Albums chart, up from No. 3 a week earlier. Castro performed at the Billboard Awards alongside José José.

Also moving up was "Don Omar Presents Meet The Oprhans," which went 13-7; Gloria Trevi's "Gloria!" moving 10-9; and Marc Anthony's "Iconos" moving 26-20. Other titles not related to the awards also saw small sales upswings, presumably because of Mother's Day traffic in stores.

On the Latin Digital Songs Chart, Don Omar's "Danza Kuduro" remained at No. 1 with sales jumping by almost 8,000 downloads, according to Nielsen SoundScan. "Danza Kuduro's" upswing can be attributed both to Omar's Billboard performance as well as to it being featured in the "Fast 5" soundtrack.

On the Hot Latin Songs chart, Mana's "Lluvia al Corazon" continues on the top spot, closely followed by Prince Royce's "Corazon sin Cara." Mana's "Drama y Luz" also continues at No. 1 on the Top Latin Albums chart.
