My list will be temporary since there's a bunch of stuff I still haven't heard. After I see what I get for christmas the list is VERY likely to change
I'm putting 10 albums on the list but I choose to separate them into favourites, and the rest instead of precise ordering:
Favourites of 2015:
Waltari - You Are
Sukekiyo - Vitium
Christian Mistress - To Your Death
Joanna Newsom - Divers
Tori Amos - the Light Princess Original Cast Recording
Olga Bell - Incitation
Other very good albums of 2015:
Helloween - My God Given Right
Gospel of the Witches - Salem's Wounds
Jenny Hval - Apocalypse Girl
Faith No More - Sol Invictus
A good year for music and still getting better, but 2014 won't be topped for a while in my book, probably.
