Songs featured within "Valley Girls" were taken from both the Los Angeles punk rock scene and mainstream 1980s hits in order to represent the two worlds surrounding character Lily Rhodes. "Jumping between these two worlds is important to the show. Lily is living with her sister in the Valley and kind of hanging out in the punk rock scene, but she and her sister come from a wealthy family and their parents are more aligned with a Pacific Palisades/Beverly Hills/Malibu, Less Than Zero world. So her struggle ... is to try and figure out what kind of world she wants to be in", says Savage. Music supervisor Alexandra Patsavas oversaw music selection for the episode. With the exception of Fountains of Wayne's "Prom Theme" (1999), every song featured within "Valley Girls" was released prior to or in 1983, the year in which Lily's flashbacks take place. Savage explains that the show makers hoped to introduce modern audiences to bands and music they had not known before. No Doubt makes an uncredited guest appearance during the episode as a fictional band called "Snowed Out", a play on words of "No Doubt". During the cameo, part of the band's return to music after a four-year hiatus, No Doubt premiered their cover of Adam and the Ants' "Stand and Deliver", the band's first new song in five years. The band performs in the Sunset Strip club where Lily meets Carol for the first time in a year.
