DnD boss music!

Hay gal hay! So I play dnd with my uncle, aunty, and their friends. I want to know if anyone has some good boss music reccs? It can be from lik ANY game idc. Obviously I could just look up "cool boss music or something but that's pretty lame. And as IMACULATE as they are, I can't just keep listening to Gladius and We've Got Hostiles on repeat 🤣 it would especially help if the music gives 40k vibes since we're playing a warhammer 40k campaign rn 😘 thxxxx!!
