"Vivir" (Live) is the fourth single of Belinda's debut studio album Belinda.
The song served as the theme for the telenovela Corazones al límite (in which she would also act for a short time), and quickly gained airplay in the charts. The acoustic version was included on the CD soundtrack from Corazones al límite.
The music video was directed by Alejandro Lozano and released in September 2004.
The Greek-American singer Kalomoira recorded the song in 2004, under the name "Someday", for her self-titled debut studio album.
