This contemplative track was written for The Divergent Series: Insurgent movie and features on the film's accompanying soundtrack. It sees M83 mainman Anthony Gonzalez teaming up with Haim. "We've been fans of Anthony Gonzalez and M83 for a long long time so when he reached out to have us sing on the song we were ecstatic," the girl group told MTV News of the collaboration. "We had the best time in the studio with him, it all happened so fast and was so easy and natural. We are so excited to be a part of this movie."
M83 have been involved with the Divergent franchise before. Their track "I Need You" appeared on the soundtrack for the first film, Divergent, which was released in 2014.
The Isley Brother's song, "Contagious," peaked at #19 on the Billboard Hot 100. This meant that the band of brothers became the first group to score a Top 50 hit in six consecutive decades on the chart.
It was never a big hit, but "She's A Rainbow" became one of the most popular Rolling Stones songs in the digital age when it started showing up in commercials (iMac, Photoshop), and TV shows (American Horror Story: Coven, Ted Lasso).
