Left and Right (Feat. Jung Kook of BTS)

This poppy post-heartbreak song finds Charlie Puth and BTS' Jungkook consumed by thoughts of their former lovers. The memories of their time together haunt the pair and they can't erase them from their minds.

Charlie Puth produced "Left and Right" himself and co-wrote it with his go-to writing partner Jacob Kasher Hindlin ("Attention," "How Long," "Light Switch"). "It's about me singing about the inside of my brain, how these memories will haunt me from the left side of my brain to the right side of my brain," Puth explained on the Elvis Duran Show.

This marks the first collaboration on disc between Charlie Puth and Jungkook. However, both artists shared the stage together when they jointly performed Puth's track "We Don't Talk Anymore" at the 2018 MBC Plus X Genie Music Awards in Incheon, South Korea.
