Bruno Mars has another feather in his fedora…

The 27-year-old part-Puerto Rican singer has earned his first No. 1 album on the Billboard 200 chart.

Mars’ sophomore album Unorthodox Jukebox reached the top spot after the set, largely fueled by sale pricing by Amazon MP3, sold 95,000 copies in the week ending March 3. It’s a week-to-week gain of 96%, according to Nielsen SoundScan.

On Tuesday, February 26, the digital retailer offered several albums for only $1.99, including Mars’ latest effort.

Discounted sales of Unorthodox Jukebox and the rest of last week’s other Amazon MP3 $1.99-priced titles count toward their weekly total because the albums have been out for more than four weeks. Billboard doesn’t count sales of albums priced below $3.49 in their first four weeks of release.

Unorthodox Jukebox was released on December 11, 2012. It debuted at number two on the Billboard 200 with sales of nearly 200,000. As of March 2013, the album has sold 960,000 copies.

The album’s first single, “Locked Out of Heaven,” reached No. 1 on the Billboard Hot 100.
