I've heard a lot of solid VGM albums with many enjoyable tracks from the year, but these are the ones I have tagged as five star:
"Apocalysis Noctis" [Final Fantasy XV OST] https://www.youtube.com/watch?v=UGq5KNZxz7A
Final Fantasy XV OST is my top VGM album of the year not for overall consistency (in which it's lacking) but because its best hour or so is easily the most dramatic of the year. And "Apocalysis Noctis" is the best of its best, an epic orchestral-choral battle theme that belongs among the series classics.
"The Hydraean's Wrath" [Final Fantasy XV OST] https://www.youtube.com/watch?v=mddVVnnNung
Another adrenaline-pumping orchestral-choral battle theme from FFXV, this one with a great brass fanfare to boot.
"World of Warcraft - Invincible" [The Greatest Video Game Music III: Choral Edition] https://www.youtube.com/watch?v=dzXc96XwiIM
A surprising number of excellently arranged, beautifully performed choral pieces can be found on this album. Among the best of them this exquisite version of a classic Warcraft theme.
"Dragon Age Inquisition - Main Theme" [The Greatest Video Game Music III: Choral Edition] https://www.youtube.com/watch?v=u2P0q-BmPKs
Another exquisite rendition of an already excellent choral theme. Lead vocalist Myrra Malmberg's performance in this track in particular is something special.
"Whisper to the Heart" [I am Setsuna OST] https://www.youtube.com/watch?v=13wnmY1fliE
Possibly the most pretty and poignant piece (particularly the ending) in a very pretty and poignant piano album.
"The Red Thread" [Unravel OST] https://www.youtube.com/watch?v=pIEN_BaicI8
The most contemporary piece in this somber, Swedish folk music inspired album is still entirely unique (not to mention moving).
