"Until the End of Time" is a song recorded by American singer-songwriter Justin Timberlake from his second studio album FutureSex/LoveSounds (2006), written and produced by Timberlake, Timbaland, and Nate "Danja" Hills. The song was later re-recorded as a duet featuring American singer Beyoncé, which was released as a single on November 13, 2007 and included on the Deluxe Edition of the album. It reached the top 20 on the US Billboard Hot 100, being the sixth single from the album to do so, with Timberlake becoming the only male artist in the decade to achieve this. During the concert tour FutureSex/LoveShow, Timberlake performed the song as a piano solo.
In his review for Entertainment Weekly, Michael Slezak opined the single "sounds like another smash. The original flavor was already a treat —a stripped-down slow jam with a gorgeously simple melody." For Complex, Tannis Spencer wrote, "Justin and Beyonce got nice and comfy on this ballad and complement each from start to finish. The beat is slow with an accompanying string section that serves as the perfect backdrop for when Justin hits his high notes.. The record has a sultry sound which helps offset the super futuristic sound on the rest of the album."Billboard editor Adelle Platon described it as a "dreamy love song." Quentin B. Huff of PopMatters wrote that "Until the End of Time" is heavily reminiscent of Prince's work, adding "both songs (with "Sexy Ladies") are album highlights, but they don’t seem to strive for the same level of innovation as other songs in the set."Sputnikmusic's Amanda Murray called the song "excessively bland."
In the United States, the solo version of "Until the End of Time" entered the top 40 on the Billboard Hot 100 for the chart issued October 20, 2017, making him the first solo male artist that decade to spawn six top 40 singles from the same album. The previous male soloist to achieve that feat was Michael Jackson with Dangerous, which generated seven top 40 Hot 100 entries during 1991-1993. The previous album overall to do so was Shania Twain's Come On Over, which had six top 40 singles during 1997-1999. The same week, the song entered the top five on the Hot R&B/Hip-Hop Songs chart.
Eventually, the song (duet version) became the sixth US top 20 entry from the album and Timberlake became the first to do that since Michael Jackson in 1991.
It also became Beyoncé's highest charting single on US Adult R&B radio peaking at number 2, until "Love On Top" in 2012.
