It's a Wonderful Music Sampler
Not only did people who went to the Square Enix Party get to try a bunch of new games-- and, well, a bunch of new releases of old games-- but they also got a bounty of free promotional stuff, including the set of CDs seen above. It contains songs from the soundtracks of two Final Fantasy spinoffs for the PSP, and from It's a Wonderful World, which is more in line with our interests.
The CD's have been ripped, and we've got the Wonderful World sampler available for download. It's J-poppy and synthy! Is it ever synthy.
