"X Última Vez" (read as "Por Última Vez" in Spanish Internet and instant-messaging slang; English: "For the Last Time") is a song by Puerto Rican rapper Daddy Yankee featuring compatriot rapper Bad Bunny, released as the third single from the former's eighth and final studio album, Legendaddy, on April 6, 2022. Its music video, shot in New York City in March 2022, was directed by Mexican director Fernando Lugo and depicts "futuristic visuals" in which both artists perform the track in a "dystopian-looking stage" and a "video game-like setting." It was written by Daddy Yankee, Bad Bunny and Puerto Rican producers Juan "Gaby Music" Rivera, Ovimael "OMB" Maldonado and Tainy, and was produced by Daddy Yankee and Tainy.
It is a reggaeton song with lyrics about "wanting to rekindle old flames" one last time and "finally saying goodbye to a relationship," and its title has a double meaning by also referring to the last time they will collaborate, since Daddy Yankee announced in March 2022 that he will retire from music after the end of his farewell concert tour. It was included among the album's best tracks by music critics and received the Top Song – Pop Urban award at the 3rd Premios Tu Música Urbano. Commercially, it reached number 23 on the Billboard Global 200 and the top 10 in 10 countries, as well as the top 20 in five others. It was the only song from Legendaddy to enter the Billboard Hot 100, peaking at number 73. It was certified triple Latin platinum in the United States and gold in Spain.
