Like all of the music of this game series, this one is great. Not as good as some of the Warlords of Draenor songs, but the Canticle of Sacrifice song here does it for me. Mainly because of the story element tied to it.
I like the soundtracks on all the albums and all but I'm still waiting for the Mists of Pandaria soundtracks to be put back on the list. It used to be here with the other soundtracks but it's been absent from the list for some time now.
No matter where the game seems to go, WoW always manages to have an impressive soundtrack. Wish they would release actual full soundtrack collections with every piece of music though, always notice some piece never make it while others are seamlessly merged together.
