"Until You Were Gone" is Chipmunk's sixth single and features Dutch singer Esmée Denters. The track is the first single from the platinum edition of I Am Chipmunk. The single was recorded in January 2010 with producer, Fraser T Smith, and songwriter Ayak Thiik. On 19 April 2010, BBC Radio 1Xtra DJ MistaJam announced on his Twitter that he would play "Until You Were Gone" for the first time on the radio, and later premiered it on the radio. Chipmunk revealed that he wrote this song about a girl called Carys Hughes.

Robert Copsey of Digital Spy gave the song a positive review stating: "As far as collaborations go, this one takes the biscuit, dunks it in a cuppa, and then cheekily asks for another. The 19-year-old rapper and the Dutch Timberlake protégé hardly seem like the most obvious doublet, but they've defied the odds on this trailer single for Chipmunk's repackaged I Am Chipmunk LP. According to Chip's twitterings, he asked Denters personally to feature on the track after holding it back for The Right Voice. It's a tale as old a time. To be fair though, he wasn't wrong - together they sound like a match made in hip-pop heaven. As Chip mourns over losing his Mrs, Denters swoops in to croon: "I didn't know how much I missed you / Until you were gone, gone, gone." The track's catchy hook is matched by Esmee's silky-smooth vocals, a welcome surprise after her somewhat underwhelming solo singles. Chipmunk hasn't broken rank from his winning formula here, but thanks to the sharp lyrics, that addictive melody and some typically clean Fraser T Smith production, he's easily forgiven." .
