I still haven't received my limited edition but a friend has sent me a screen of the downloadable version of the European sound selection. And it turns out that it has more tracks than the vinyl ! Actually, that's the same tracklist than the Australian CD (and maybe the Japanese ? I haven't found its tracklist yet).
And it also seems to have composers credits under the "artist" tag !
Sadly, the ACE+ main game songs credits still aren't separeted between ACE and Kenji Hiramatsu.
