Zara Larsson sings here about breaking up with her former boyfriend in order to enjoy being single. She feels much better off without the cuffs of being in a relationship and is now loving the "lush life."

Larsson debuted the tune during a concert at the Gröna Lund amusement park in Stockholm, on May 8, 2015. The song topped the charts in Sweden for five weeks, becoming Larsson's second #1 single in her home country. It also reached the Top 5 in numerous other European territories.

The song was written by a sextet of Swedish songwriters and producers: Emanuel Abrahamsson, Linnea Södahl, Iman Hultén, Markus Sepehrmanesh, Christoph Bauss and Fridolin Walcher. It came together at a writing camp in Stockholm. Larsson explained to Genius:

"A writing camp works like this: A lot of people - producers, writers, top liners—they come in. Let's say 25 people, 30 people. We have a studio complex in Stockholm, so we've got a lot of studios. We just put a little group in every room. That's the way we do it.

By the end of the week, we all play the songs for each other. 'Lush Life' was really the only song that stood out that I was like, 'Whoa. What is this?' It just had a really nice vibe to it, and I love it so much. We were approaching summer, and it's a very good summer song."

A clubbier reworking of the track featuring British rapper Tinie Tempah was released on February 26, 2016.

Cosmetics company Clinique used acoustic, dance, country, and pop versions of the track to promote four new makeup lines.

The song is about having fun and living a lavish life. Larsson explained: "It has a really nice message: live my day as if it was the last. Basically, just do everything you want to do with no past. Have no regrets. Live in the moment and try to enjoy it as much as possible. When I perform, it's really what I'm doing on stage. I enjoy it so much. It's my favorite place in the whole world."
