Camila Cabello's debut solo single is a moody, empowering anthem about uplifting herself during a difficult period in her life.

Ain't no crying in the club (Hey, hey)
Let the beat carry, your tears as they fall baby
Ain't no crying in the club (Hey, hey)
With a little faith, your tears turn to ecstasy

Cabello had a very public split from her group Fifth Harmony in 2016.

Asked during a Beats 1 interview why this was the first song that she wanted her fans to hear, Cabello replied:

"That was definitely part of the healing, this song. The lyrics are very hopeful, but the beat is very intense. I never just want to make a straight up happy song, it's just not in my nature. The beat has this very intense, cathartic feeling about it. It was kinda like what the writing process was saying to me. So of the lyrics are 'Let the music lift you up, like you've never been so high. Let the music lift you up, like you've never been this free.' It felt like what this album and this music was."

Cabello wrote the song with Sia, Benny Blanco, Cashmere Cat and Happy Perez, with the latter three serving as producers along with Matt Beckley.

The melody of the "I won't" portion of the song's hook is borrowed from the pre-chorus of Christina Aguilera's 1999 break-out tune "Genie in a Bottle."

The Emil Nava-directed video sees Cabello reeling from heartbreak before dancing away the pain in the club. The clip starts off with 1:45 minutes of another The Hurting. The Healing. The Loving track "I Have Questions" before breaking into this song. Cabello spoke about the clip with Complex, saying,

"This video summarizes the message of my journey over the past couple years, from darkness to light, from lost to found. The director Emil Nava and I put our hearts into this and we hope you like it!"

The origins of the song lie in a bathroom break that Sia took. The Aussie songwriter was writing with Benny Blanco in Los Angeles when inspiration suddenly struck her. "Sia was on her way to the bathroom and goes, 'Oh, my God, I have a really good idea for a song!'" recalled Blanco to Billboard magazine "When she came back, we did the song in 20 minutes."

After Blanco offered Cabello the song, the former Harmonizer rewrote the bridge and recorded the track. "It had a message about healing through the power of music," she said. "That theme was a key part of what I wanted for my album."
