Mouthwashing soundtrack
Martin Halldin composed the Mouthwashing soundtrack. The digital album is a separate purchase from the game. The official main theme is on YouTube, and Fangamer lists physical music editions.
What I saw
Composer credit is supported by the official soundtrack announcement and the independent Wikipedia credits. Digital and physical album prices are single-store quotes. This review did not play the game or claim to listen to every track.
Digital and physical
Digital: USD 9.99 in the log, separate from the game’s USD 12.99. Buying the game does not automatically include the soundtrack album.
Fangamer: vinyl USD 39, CD USD 15, cassette USD 15, all dated to the same log. Confirm stock on the shop.
What this page does not list
The official main-theme upload is labeled track 01. A full cue-by-cue track list was not independently checked, so this page links the album instead of publishing an unverified list.
In-game, Polle’s voice is speech spliced by Martin Halldin. That is a character fact, not a soundtrack SKU.
