@phuzzybond I think if it is accompanying gameplay from their game and it is acknowledged that you do not own it you are fine but I don't really know.
This is not legal advice
you could always use the youtube music search and see if sea of thieves is listed. If it is, it will tell you what you can and cant use. It's a very helpful tool.

edit.
you could also upload the song as a private listing, wait a little while and see if you get a notice via the yt content ID. it will also tell you what the copyright holders will allow you to do, whether to remove or if they will place ads on your video.
