I wasn't keeping track of everything I was listening to last year, though my favorite album was Ghost's new album, "Skeleta". It was an album that grew on me, as other than a few particular songs, it didn't really hit me, especially coming off of Impera, but songs like Peacefield, Satanized, Lachryma, are super strong songs for me. It's still below albums like Impera and Meliora for me, but still a solid album.
Can't remember if I listened to much else, I did listen to the new Castle Rat album, which is good, but I didn't listen to it enough compared to something like Skeleta and I had just found the band last year, so it was more just listening to that and their previous one at the same time.
