The soundtrack from Saga: Rage of the Vikings by French developer Cryo Interactive.
This is a game from 1998 or so, I remember buying it because the screenshots on the back of the box looked like Age of Empires. Back then I'd buy anything that looked like Age of Empires, Diablo, or Baldur's Gate/Fallout, etc.
It's kind of an Age of Empires clone, but more mythologically inclined (you can play as vikings, elves, trolls, giants, etc.) but the music (playable CD on a game disc) was terrific.
Sadly due to some copy protection nonsense the game stopped working back when Win98 was still the most current OS, but I kept the game/disc just for the music.
