We have a proper retail CD release of Super Mario Odyssey Original Soundtrack - four discs no less - coming up for release in Japan on Feb 28. It's currently up for pre-order at Play-Asia and the usual other importers.

There's also a somewhat scantier digital release, Super Mario Odyssey Sound Selection, currently available on iTunes. It clocks out at 39 minutes with 12 tracks - four of which are "Jump Up, Super Star!"
I'm sure several people here have played the game by this point. What were your thoughts on the music?
