Frontman Nate Reuss revealed that the track was originally intended for their 2011 album Some Nights, but they left it off after it featured an uncleared sample.

"We got really dejected and put it away until Lena [Dunham] called," Reuss told Rolling Stone. "I ended up rewriting the chorus and actually like it better than the sample now!

"We recorded most of this in Italy on a day off from tour and I just remember us eating an Italian feast at the studio and barely being able to communicate with the engineers, which was kind of cool because it eliminated all small talk and put the focus into the song."

The second season of Girls returns to HBO in the US on January 14 and will be aired a day later on Sky Atlantic in the UK.

The official soundtrack will be released in the US tomorrow (January 9), and features further cuts from Santigold and Robyn.
