Does anyone have a collection of the tracks excluded from the OST (such as the 80s music and trailer music and etc)? I'm assuming at least most tracks can be found elsewhere (Nuclear, for example, is available on the album Man on the Rocks), so if no one's made a collection of the music I'm looking for yet, a list of songs not on the OST would also be helpful. Thank you in advance!

Hmmm. Looking at VGMDB, some of (but not all) the tracks I was thinking of are on the OST after all...but don't appear to be in the album download links I've found...

The uploaded version is the itunes version, therefore the tracks are missing.
Just wait for the official japanese CDs to be ripped and uploaded.
