What song would you listen to for a boss in Elden Ring

So context I give myself pretty weird rules when I play Elden ring. I’ll do the standard no summon or sorcery but I also do things like keeping my beginning esthetic and if I start a boss fight I must beat it before continuing without changing my initial load out.

Now what does that have to with my question. Well I’m trying to listen to a song on while fighting a given boss. For example when i fight rellana in the DLC again I’ll be listening to bye bye bye by NSYCE until I beat her. So I’d like to get any suggestions I can for songs to use. I’m open to anything from beethoven to beyonce.

Thank you to all that reply.
