While it was called "Sonic Unleashed" in the USA, it was called "Sonic World Adventure" elsewhere. As you can tell, this isn't the USA version of this official sound track disk. It's somewhat subtle (not using a picture of Sonic at all) going with a variety of broken up/weathered looking fonts for the title, and just placing it over a planet-rise panorama with stars. It contains all the songs from the game itself & is 3 disks long.
The cover seen at the left, is actually a box-container for some awesome new cover art seen at the right. This is the actual part that holds the discs. It is in the Sonic District collection and images of all contents will be updated in the future.
