Unorthodox Jukebox

Unorthodox Jukebox is the second studio album by American recording artist Bruno Mars. It was released by Atlantic Records on December 7, 2012, as the follow-up to Mars' 2010 debut studio album Doo-Wops & Hooligans. The album was initially planned to be more "energetic" than his previous material; Unorthodox Jukebox ultimately presented a wide range of styles, such as reggae rock, disco and soul music. The singer co-wrote the whole album and worked with several past collaborators, while enlisting new producers and guest vocals. Much of Unorthodox Jukebox revolves around the theme of relationships, with more explicit lyrics and subjects than his previous material. Critical response to Unorthodox Jukebox was generally favorable; many reviewers compared the work to that of his previous album, while others deemed the lyrical content as shallow and lacking of depth.
On December 4, 2012, the album was available to listen to in its entirety for a week before the release. The album debuted at the second spot in the US Billboard 200 with 192,000 copies sold, becoming Mars' best opening week to date. Later, the album peaked at number one on the chart becoming Mars first album to do so. The record peaked at number one in Australia, Canada, Switzerland, and the United Kingdom. Unorthodox Jukebox became Mars' fastest-selling album in the UK and third in 2012, the third best-selling album in Australia in 2013, and the fifth best-selling album in the United States in 2013. The International Federation of the Phonographic Industry (IFPI) reported that Unorthodox Jukebox was the fourth best-selling album in the world in 2013, with 3.2 million copies sold. It has globally sold 6 million copies as of January 2015. The album won the Grammy Award for Best Pop Vocal Album at the 2014 ceremony.
The release of the album was preceded by the release of one single. "Locked Out of Heaven" was released on October 1, 2012 as the album's lead single. It became a commercial success on music charts all over the world and topped the US Billboard Hot 100 chart for six consecutive weeks. In between the release of the lead single and the album were the releases of promotional singles "Young Girls" on November 6, "Moonshine" on November 19 and "When I Was Your Man" on December 4, 2012. The latter was released as the album's second single, one month and half later, on January 15, 2013 and became Mars' fourth single to top the US Billboard Hot 100 and experienced similar mainstream success as the lead. "Treasure" debuted on May 10, 2013, as the album's third single and was a moderate commercial success, peaking at number 5 on the US chart. "Gorilla" and "Young Girls" were the fourth and fifth singles, respectively. Unorthodox Jukebox was further promoted through the Moonshine Jungle Tour.
