"No Debes Jugar" was written by Selena y Los DinoskeyboardistRicky Vela and Selena's brother, principle record producer and songwriter A.B. Quintanilla III. It was produced by Quintanilla III and Argentine music producer Bebu Silvetti. The song was intended to be one of three studio tracks for Selena's Live! (1993) album. Vela had wrote most of the lyrics while touring with Los Dinos in the 1992-93 period. Quintanilla III later co-wrote the song after Vela finished the lyrics. Quintanilla III only made a few adjustments to the song and began adding music notes for pre-production.
