BLU-SPEC CD2: On 28 September 2012, Sony Music Entertainment Japan announced "Blu-spec CD2" or BSCD2, a progression of the Blu-spec CD format which employs a more precise BD cutting machine, a master disc that is made from the same smooth material as silicon wafers for chip manufacture, and a different recording layer material for the master disc. Sony refers to this process as "Phase Transition Mastering". A Blu-spec CD can be played on all CD players and does not require a blue laser to be read. The same holds true for Blu-spec CD2 discs.
I believe LLL said that someone (not LLL) would be releasing both Ghostbusters scores, or at least the 2nd one, and with #2 coming to Blu-ray soon the timing is certainly right.
It amazes me many times how bad the timing is that record companies releases soundtracks even when a movie has it's anniversary celebration long ago.
The theatrical 4k release is later this month for the movie. The Blu-ray anniversary editions come out mid September. I'd think they'd want to time the releases more with those things than the literal anniversary date of the initial release.
