The sparkling and swinging Easy Virtue soundtrack includes 17 tracks taken from the film, all of which have been re-recorded. It features popular hits from the 20s and 30s such as "When You're Smiling" and "Let's Misbehave" as well as modern day tracks such as "Car Wash", "Sex Bomb" and "When the Going gets Tough" (which have been made to sound like they are from the same era). There are several new compositions written by Marius de Vries including a dramatic Tango.

The album was recorded by Marius de Vries, whose credits include Bijork, Madonna, Rufus Wainright, Josh Groban, Annie Lennox, Teddy Thompson and the soundtracks for Moulin Rouge and Romeo and Juliet.

Members of the cast sing on four of the songs: the opening title track "Mad About The Boy" is sung by Jessica Biel. Ben Barnes appears on two Noel Coward songs "A Room With A View" and "I'll See You Again", and Colin Firth joins in with them both for an all star end title track "When The Going Gets Tough, The Tough Get Going".

Marius de Vries has assembled a fantastic team of musicians for the album including Dave Rowntree (the drummer from Blur), Mike Smith (keyboard and sax player for the Gorillaz and The Good Bad and The Queen), Chris Storr (Trumpeter for Jools Holland), violin player Sophie Solomon from Oi Va Voi, and internationally renowned pianist, Jim Watson.
