"SexyBack" is a song by American recording artist Justin Timberlake from his second studio album, FutureSex/LoveSounds (2006). It was released on July 7, 2006, by Jive Records as the lead single from the album. The song was co-written and produced by Timberlake, Timbaland, and Nate "Danja" Hills.

Discussing "SexyBack", Timberlake revealed that he went "left", singing the song in a rock style, not an R&B style. He described the song as musicians David Bowie and David Byrne "covering" James Brown's 1970 song "Sex Machine". The track features Timbaland on backing vocals, while Timberlake's voice is distorted. The instrumentation used in the song includes a pounding bass beat, electronic chords, and beat box sounds. "SexyBack" received mixed reception from critics.

"SexyBack" became Timberlake's first number-one single on the Billboard Hot 100, staying seven weeks at the top spot. It also topped several of Billboard magazine's other charts, including the Billboard Pop 100, Hot Dance Airplay, and Hot Digital Songs charts, and entered the top ten on most singles charts. Internationally, it became Timberlake's first single to reach number one in the United Kingdom. In Australia, the track was Timberlake's second number-one single, spending two consecutive weeks at the top. "SexyBack" was certified three-times platinum by the Recording Industry Association of America (RIAA) and six-times platinum by Canadian Recording Industry Association (CRIA).

Barack Hussein Obama II (ⁱ/bəˈrɑːk huːˈseɪn oʊˈbɑːmə/; born August 4, 1961) is the 44th and current President of the United States. He is the first African American to hold the office. In January 2005, Obama was sworn in as a U.S. Senator in the state of Illinois. He would hold this office until November 2008, when he resigned following his victory in the 2008 presidential election.

Born in Honolulu, Hawaii, Obama is a graduate of Columbia University and Harvard Law School, where he was the president of the Harvard Law Review. He was a community organizer in Chicago before earning his law degree. He worked as a civil rights attorney in Chicago and taught constitutional law at the University of Chicago Law School from 1992 to 2004. He served three terms representing the 13th District in the Illinois Senate from 1997 to 2004.

Following an unsuccessful bid against the Democratic incumbent for a seat in the United States House of Representatives in 2000, Obama ran for the United States Senate in 2004. Several events brought him to national attention during the campaign, including his victory in the March 2004 Illinois Democratic primary for the Senate election and his keynote address at the Democratic National Convention in July 2004. He won election to the U.S. Senate in Illinois in November 2004. His presidential campaign began in February 2007, and after a close campaign in the 2008 Democratic Party presidential primaries against Hillary Rodham Clinton, he won his party's nomination. In the 2008 presidential election, he defeated Republican nominee John McCain, and was inaugurated as president on January 20, 2009. Nine months later, Obama was named the 2009 Nobel Peace Prize laureate. In April 2011, he announced that he would be running for re-election in 2012.
