For those who remembered the Devastation console game, and liked the music (because it was done by the legendary Vince DiCola), eleven tracks are available for purchase digitally, from a few different sources...

Amazon America (not sure if it is just for those with an American account)
Spotify
Apple Music
Tower Records Japan

Track list.
01. Welcome To The Proudstar
02. There It Is Autobots
03. Operation Obliteration
04. Save Cybertron
05. Fate Of Cybertron
06. Nova Prime
07. Save The City
08. Transformers Devastation Theme (Mix)
09. Transformers Devastation Theme (Short Edit)
10. Transformers Devastation Theme (Instrumental)
11. End Credit (Medley)

Judging by the sampling you can get from the Amazon page, four of the eleven are mostly the same music... so may not be great value.
