The soundtrack to The Perks of Being a Wallflower was released by Atlantic Records on September 11, 2012, a month before the film's release.[35] The film's music was chosen by the film's director Stephen Chbosky and music supervisor Alexandra Patsavas, while the incidental music was scored by Michael Brook.[36] The score album was released September 25, 2012.[37]
Chbosky wrote on the album's liner notes, “I’ve shared them with friends. And they have shared their favourites with me. Some of the songs are popular. Some of them are not known by a whole lot of people. But they are all great in their own way. And since these songs have meant a lot to me, I just wanted you to have them as a soundtrack for whatever you need them to be for your life.”[38][39]
