The recent PS5-centric redesign of the PlayStation Store has nuked the current sale link (ref.
https://store.playstation.com/#!/en-...ADOTBEASTOSTUS).
Searching for "shadow of the beast" on the PlayStation Store from a desktop web browser gives you a result for
the game itself but no way to purchase, let alone a mention of, the soundtrack.
This is also the case for
Tearaway Unfolded and
Detroit: Become Human, but oddly not for
Everspace, which still has its own discrete soundtrack page with purchase button.
I presume you can still search for and purchase these soundtracks from a PS4, but I currently have no way to test this.
