Dude I m not forcing anything on uI've finished the game and I've heard the OSTs in the all the above mentioned contexts and it's still not THAT great. GOOD but not as good as you think.
And 2ndly NO, a good OST can stand on it's own without context (sometimes having gampley on does make a huge diff but not in this case tbh), for example, I haven't played persona 5 yet but it's OST stands out on it's own without any gameplay context, another recent example of a good orchestral OST would be the WItcher III's ost. I started listening to that months before I played the game and I kept listening to some tracks on it regularly or quite a while.
But hey that's just my opinion
I mostly agree with you too. But still this game has great OST in my opinion becoz that was the only thing that kept me interested in gameplay which from route B onwards becomes way too repetitive to be fun.
