[Poll] What is your favourite boss OST?

Hey guys, I'm a newcomer to the series, and have just beat the Soul Of Cinder after 1000 tries. The thing I love most about the game is the incredible OST for the bosses, so I was wondering which OST you guys liked most? Since there are many great ones, I decided to toggle the multiple option thingy. I personally love the OST from Abyss Watchers, Soul Of Cinder and Pontiff the most. Have a great day :)

Edit: Seems like I forgot to add the Dancer to the poll, so I created a new one. Sorry if you already voted :/
