PySolFC - FOSS Game Soundtrack
PySolFC is a very, very comprehensive free and open source solitaire program notorious for including over 1200+ card and tile solitaire games and variations. Developed in Python (hence the name), PySolFC is available for Windows, macOS, GNU/Linux and Android under the terms of the GPL-V3 license.
The standard PySolFC distribution doesn't include any music files to keep download sizes low, and the program itself will auto-play any MP3 or audio file placed in it's music subdirectory. However, an "official" music pack is available that adds a pleasant selection of MOD tracker files by Carl Larsson (aka Nightbeat) to the game.
