X 100pre (an abbreviation of "Por siempre" in Spanish, meaning "Forever"[A] and stylized in all caps) is the debut studio album by Puerto Rican rapper Bad Bunny.

[5] Following the release of the album, Bad Bunny revealed in an Instagram live video that he was not working under his first label Hear this Music and his previous manager DJ Luian because he was not able to release albums under his previous management.

[6] The album cover design was created by Sergio Vazquez and "inadvertently" gave Bad Bunny the idea for using the "third eye" in many of his future shows.
