Hi KerrytheBob, we're really glad you enjoy the game's music! Pub Jazz is an original piece composed by Transfurom for our game. Unfortunately we've been unable to include it on the Steam Soundtrack because that is specifically a collection of CheasyDino's work, who did the remainder of the original score for the game. At the moment Pub Jazz is only available in the in-game music room. Sorry about that! I'll let Transfurom know you enjoy it!
