Music (Unravel)

I think many have noticed that the music in the game is good, and maybe even some of you, like me, are very deeply imbued with it.
So, I would like to have this sound on hard. But I can't find it anywhere, can anyone tell me where to look or give a tip where to look (I'm just not sure that direct links are allowed)
I only know that the developers are not planning to release music separately (and in vain), and I know what can be listened to in vk but the quality and completeness of those tracks is questionable.
