"Your Life Is a Lie" is the second single released from the third album by MGMT, which was released as an instant download with the album pre-order on August 6, 2013.
It is also the first time that the band has used a hashtag to promote any single; in recent posts on their social networks the hashtag "#YLIAL" can be seen, acronym for the title of the song.
In an interview with XFM, VanWyngarden explained the meaning behind of this song: "Your Life Is a Lie in particular was never meant to be directed at our fans or anybody in particular. What it's meant for more is to be utilized as a kind of weapon that you can direct towards whoever you want and it's supposed to be an empowering song."
In the July 2013 issue of NME magazine, the song is explained as "a burst of clattering, misanthropic buzz-pop vitriol"; while Relix Magazine explains it as a "lyrically dark song". In this same interview, VanWyngarden explains that he wrote the song "while tripping hard on acid by a fire".
On August 5, the band premiered the music video for this song, which was directed by Tom Kuntz; the promotion of the video it's accompanied with an interactive kaleidoscopic video embedded on their official website. A day after, the single was given as a free download with the album pre-order on iTunes.
