Could be a bootleg - I notice the discs say 'Square Enix' on them - the FFVII OST was published by Digisoft (a semi-autonomous company that's since gone out of business), long before the Square/Enix merger - it should say 'Squaresoft' on them. There are tons of bootlegs of it going around - if it says anything other than Digisoft it's a bootleg.
Just want to point out Square/Enix actually reprinted it: SQEX-10001~4 | FINAL FANTASY VII Original Sound Track - VGMdb (

While there are tons of bootlegs going around, I'd say the one in that picture is legit.
