The Great Gatsby.

  1. Swanee - Al Jolson
  2. West End Blues - Louis Armstrong
  3. Rhapsody In Blue - Paul Whiteman featuring George Gershwin
  4. Ain't Misbehavin' - Fats Waller / Louis Armstrong

 I picked these 4 songs from the 1920s because they are 4 of the most popular songs from that era. It is very likely that Gatsby and his guests would have listened to some of these songs during parties or other social events.
