Neir Automata has an absolutely banging soundtrack. You need to "finish" the game I think 3 times to see the final ending. Push through the run as 9s it is worth it. The ending has all the feels and the ending song is with it is phenomenal.
To The Moon has a beautiful soundtrack and a story which made me cry. It's not a long game, I highly recommend it.
Syonara Wild Hearts is a video game music album. It's really simple mechanically but the songs are great and it's a proper Zen game.
Journey has a wonderful sound track, just get to like level 3 where your doing the big slide downhill and tell me that's not magical.
Similar to Journey (but not quite as good) is Gris.
Bastion has some excellent songs and is a short experience.
Terraria has a brilliant soundtrack and great gameplay, very little story though. Great in multiplayer so find a friend.
Death Stranding has some great songs, a bit to spread out though. The story is Kojimas usual eclectic madness but I enjoyed it.
