Kerli recalled thinking to herself upon hearing of
space tourism, specifically the project of
Richard Branson (who Kerli admires) "This is incredible! Who would have known I can witness this during my lifetime? I should write a song about this and it should be called 'Zero Gravity'." Kerli began to write the song shortly before abandoning it. A year later, Kerli was scheduled for two studio sessions while in
Stockholm. With only five hours remaining in the second session, Kerli "had kinda given up on the idea that any producer would actually get [her] and become [her] musical soulmate" before meeting her "favorite producers and friends for life", Svante Halldin and Jakob Hazell (the team known as "SeventyEight", who also collaborated on "Lucky Ones" by Kerli). Kerli played for them the
Wolfgang Gartner song "Space Junk" (2010), stating she "wanted to channel that but also mix some ethereal elements into that. Something like
Enya or
classical music. Something that sounds like angels on
acid." The song was finished in the final hours of the session. Kerli stated the lyrics of the song were written in "the honor of" the air spirit,
sylph, and that song is about "merging with the spirit, becoming all love", continuing to say she "[loves] the air element and it kinda seems to be something that keeps popping up throughout the music [she makes]." The song begins with a simple 10-note piano chord before being picked up by a
synthy drum beat. The
pre-chorus features a dizzying up and down feel before the chorus merges the drum beat with the piano chord and some more prominent synths. The second chorus finds a
dubstep-like
wobble bass before the bridge brings a heavier take on the pre-chorus's dizzy feel, also containing a
drop, drawing further inspiration from dubstep. The song ends with the piano chord. == Critical reception ==
