This CD is called "True Blue the best of Sonic the Hedgehog". It seems to focus on more modern music (ie, no green hill etc) and even contains 4 bonus tracks which are re-mixes and other versions of the music . With loads of great tracks that have real variety, plus the remixes, you're really getting a cool CD if you can track this one down.
Here's the interior of the True Blue CD. The inside cover has a similar collage theme going on, this time with a dark filter over most of it, except a small shape in one corner. The CD itself has a matte white background with GC running Sonic & an after-image like effect.
