I've bought the Kompakt (twice) and the Nihon compilations, and this has some great tracks, many in fact, but 138 tracks is just too long and will take too much time to digest so much music (well, for me at least). Great idea, but I think being this long may be counter productive. Not being negative about the concept - I think it's brilliant and power to the artists & producers for donating these.
This release is too good; so many unreleased tracks...have been listening to this...amazing track selection! It's kinda long I know; but, it's certainly not boring....wish I had known about this earlier though...
