So I noticed in the patch notes for the newly released Mistlands update (for the public test branch) that new music was added, since its a new area and all. I checked the Valheim Soundtrack album, just out of curiosity, and saw that the new music was not added. Now I wasn't really expecting it to be added right away, especially since it isn't fully out yet, but I did see Hearth and Home music in the album.

My question is do they update the music available in the album as more updates go live or have the Hearth and Home soundtracks always been there?
