The Whiplash soundtrack consists of 24 tracks sequenced in 3 distinct parts: Original jazz songs written for the film, original underscore written for the film, and classic jazz standards by Stan Getz, Duke Ellington and more. There are also choice snippets of dialog included on the soundtrack that sum up the narrative of the film and help to put the music in context (à la Pulp Fiction). The Original Score & Big Band Songs were created by Justin Hurwitz. The original jazz songs were created by Grammy nominated composer, Tim Simonec.

《小情人》电影以70年代末为背景，所以加插了大量儿时玩意的片段，例如弹橡筋、跳橡筋绳、煮饭仔等等的游戏，那些似曾相识的画面，观众看到一定可以勾起不少童年回忆。
影片中亦加入了不少旧歌作配衬，其中更有香港人熟悉的《再与天比高 》和《京华春梦》，这些大家小时候耳熟能详、日哼夜哼的电视剧主题曲，令人倍增亲切感。
