Bye Bye

"Bye Bye" is a trap-filled Marshmello-produced song in which Chicago rapper Juice WRLD raps about moving on from a toxic relationship. It is a triumphant rather than miserable breakup track as his ex had made his life hell (he calls her "a demon"). Juice feels liberated having left the poisonous girl.

Marshmello made "Bye Bye" the first night he met Juice. The Chicago rapper teased the song on his Instagram in February 2019, about 10 months before his death from a drug overdose in December that year. Marshmello released the track as a single on October 14, 2022, keeping it exactly the way they made it that night.

"Bye Bye" is the third song Marshmello released with Juice WRLD, following "Come & Go" and "Hate The Other Side" from Juice's 2020 posthumous third studio album, Legends Never Die.
