A mod I made awhile back but forgot to share. This mod adds the soundtrack for all 7 seasons of Game of Thrones to the adventure editor. There's the possibility I missed one or two tracks since these were just taken from Youtube playlists and I didn't bother going back and double checking to see if I got every single one, but in total this will give you 149 new music tracks. Note that it is intentional that I did not include track 1 for seasons 2-7, as they are the show's opening theme and are thus identical to track 1 of season 1.
