"Don't Matter" is a reggae fusion–R&B song recorded by Akon for his second studio album, Konvicted (2006). The song was released as the album's third single in early 2007. In April 2007, it became Akon's first solo U.S. number-one single and second number-one overall. A crucial part of the chorus uses Bob Marley's 1979 classic "Zimbabwe". The bridge also borrows the melody from R. Kelly's song "Ignition (Remix)". This song was #31 on Rolling Stone's list of the 100 Best Songs of 2007. This song was also #81 on MTV Asia's list of Top 100 Hits of 2007.

"Don't Matter" was released in the United States in mid-January 2007. The song made its debut at number seventy-nine on the Billboard Hot 100 and reached number one after ten weeks on the chart, in large part due to its substantial airplay, the song topping the Hot 100 Airplay chart for two weeks. In the United Kingdom, it debuted on the singles chart at number forty-five, based solely upon downloads, and late peaking at number three following a physical release. Following the song's debut inside the top ten on the singles chart in Canada, it peaked at number one for a period of three weeks. As of January 2008, the song has been certified 3 times platinum for 3,000,000 digital sales. Bizzy Bone made a remix with this song, so did Candace Jones, Jadiel and Nivea.
