Heya was released on 29 April 2024 as a title track from IVE Switch, the second extended play by South Korean girl group IVE. This excerpt comes from their Music Bank performance broadcast on 3 May 2024, a stage that helped the song spread among K-pop fans online. IVE debuted in 2021 and quickly became known for confident, elegant pop concepts. Heya stayed popular in edits and dance challenges because its chorus is short, recognisable and easy to loop, keeping it in regular use by fans well beyond its release week.
