How do I separate Christmas music and spoken word from my main library in Music on macOS 15.3.1?

I am trying to create playlists that exclude things like Christmas music or spoken word mp3s from being in my main library. Every time I put my music on shuffle, a Christmas song or OTR show will loop in even though it's unchecked or only in a playlist. I want to separate that out. It looked like the fix may have been a previous iOS because there is no "add songs to library when adding to" checkbox in Music settings and advanced or any other tabs in Music that I can find. Any ideas?
