Greenlights (song)
"Greenlights" is a song by American electronic dance music group Krewella. It is the current duo’s fourth single release from their second album "Zer0", and their second number one single (as well as their 11th charted single and fifth top ten) on "Billboard’s" Dance/Mix Show Airplay, reaching the top spot in its April 18, 2020 issue. The single was used in a commercial campaign for Orangetheory Fitness that was launched in December 2019 prior to its release as a single to Dance radio in January 2020. In an interview with "Billboard", the Yousaf sisters describe  the song’s motivation theme which led to the ad campaign: "We were so inspired to write a song that exhibited the meaning of ‘more life," adding that "because we’re constantly searching for different ways to tear down our own insecurities, barriers, or whatever else gets in the way of us growing as people. Movement is so important to us, whether on stage or in any other aspect of life, and giving others a reason to push further through our music is a dream for us."
