Pérez provided an evocative account of working with Selena during the sessions for "Amor Prohibido". Pérez wrote how Selena never complained in the studio, adding that the singer was never recalcitrant towards changes. Selena would often arrive at the studio during the album's production, "hum her part a little", and then proceeded to the mall informing the band not to worry because she would "know what to do when band is ready to record." Nevertheless, Pérez explained that the band never had to approach Selena on changes in the studio as she disciplined herself and tracked her vocals while requesting a second take in order to "add little harmonies she'd create" during recording. A.B. described his own creative process during the sessions in a 1994 interview with KMOL. He would use a tape recorder to hum a melody before creating a title and concept of a song. If he caught himself humming a tune the next day "then it's catchy", and otherwise he "wouldn't use it." A.B. also requested material from Rena Dearman, former keyboardist of the group, who provided several songs. A.B. favored "I'll Be Alright" and wanted Selena to record the song for "Amor Prohibido". After it was rejected by EMI Latin because it was incoherent of the album's theme, A.B. suggested that it could be included in Selena's next Tejano recording.
