Many musicians have since recorded the song and released it on their respective albums including Mexican mariachi singer Alicia Villareal, American reggaeton performer Ivy Queen, American indie rock band Girl in a Coma, and American salsa singer Manny Manuel.

Background and composition
"Si Una Vez" was written by Selena y Los Dinos backup dancer and vocalist Pete Astudillo. The song was co-written by Selena's brother-producer A.B. Quintanilla who, along with Argentine musician Bebu Silvetti, served as producers. Keyboardist of the group, Ricky Vela retold in a 2002 interview how the band hired a professional trumpeter to record parts of the song. In the live version performed at the Astrodome for Selena’s last concert in 1995, the trumpet intro was mostly replaced with a bell synth playing the background melodies. "Si Una Vez" is a Spanish-language mariachi fusion track with influences of cumbia and Latin dance music. Author Deborah Paredez called "Si Una Vez" as having punk music undertones. In 2002, A.B. spoke on how Amor Prohibido was experimental music-heavy and commented on how "Si Una Vez" was an example of his ideas of keeping the band's image modern. The song makes use of the Guitarrón guitar under a cumbia beat.

"Si Una Vez" is written in the key of D minor and is played in a moderate groove of 84 beats per minute. It incorporates music from several musical instruments, including the piano and guitar. Lyrically, Selena reminiscences her failed relationship and wonders why she ever fell in love with an abusive partner who betrayed and left her, vowing to never allow a man like that back into her life. The lyrics suggest unrequited love and female empowerment.
