Backseat (feat. Carly Rae Jepsen)

“Backseat” is the soaring opening track off "Pop 2", and Charli’s first collaboration with Carly Rae Jepsen. Both singers had previously collaborated with Rostam, Ariel Rechtshaid, and Noonie Bao.

On the collaboration itself, Charli said:

"We spoke about this tweet that had gone viral of a picture of me, her, and Lorde. Our fans wanted us to make a song together. Then we got drunk and spoke about all these ideas we had about making a whole album together. One day, she was in the studio with my friend Justin Raisen, and I went down there. They had been partying and we were just gonna have a jam session, but she’s really fun as a person, and she has so many ideas and is a really creative and wonderful songwriter. So when I did this mixtape, I hit her up, saying, “Is this the time?” And she said yes, so I sent her the song and she was into it, wrote her verse, came back to me, and I loved it."

This song shares the theme of drowning thoughts and pain in noise and sound with the mixtape’s ninth track, the MØ featuring “Porsche.”

In an interview with Vulture, Charli said

"I met Carly through Danny L Harle because they did a song together. We were in L.A. and they had this PC Music night, which was pretty wild, actually. But Carly came with her parents , so we were all watching the show together. It was funny: Carly and her parents at this one table, me and all my friends at one table, then Tinashe and all her friends at another table. We were a gang. But I met Carly and her parents, and they were so sweet and obviously I’d been a fan."
