The album plays the first part of the loop once and fades on the second loop. So those hoping for extended cuts are going to be a little disappointed, giving that the original game only used 57 minutes. So the additional 20 minutes (technical limit of an audio CD under 80 min) that could have been used wasn't. Some tracks seem to have unnatural loop going (but it could just be me) while others have like why couldn't hear more of the song like a better flow to towards the looping before the fade. And "Cosmic Eternity - Believe In Yourself" is the standard game size version and not the extended cut. The past versions are the highlight of sound quality, sounding naturely clean (like from a DAT tape) unlike the PC version of them that has a little noise and the Sonic 1 + 2 sounding artifically clean. The dynamic range seems to sound about the same as the original game. It's has the full version of Sonic Boom - Opening Theme on it and two remixes. One of Stardust Speedway (American) with Cash Cash VS Jun Senoue and Sonic Boom with Crush40 VS Cash Cash.
Edit: CD info on Wiki. If someone wants to iron out the bugs since I'm wiki novice here, I kindly thank you.
