Personally, I really like the Morrowind music, but I haven't listened to anything from the previous two games. Skyrim's soundtrack was okay, but it felt a little boring to me compared to the Morrowind track.
What do you think of Oblivion soundtrack? I'd like to add some tracks to my wedding party playlist, that would be fun! But I also have to choose something popular like any of these songs from that article - https://www.poptop.uk.com/blog/top-tips-when-choosing-the-wedding-exit-songs/
