Morrowind, Oblivion or Skyrim? I would say regarding the main themes its Morrowind>Oblivion>Skyrim. Skyrim has a bigger variety in music by far. Skyrim has great battle themes too. Oblivion though has great wilderness themes. Very nostalgic. What do you believe?

Morrowind has the best and most memorable soundtrack.

Skyrim kinda wins for me since it has the best battle music by far. Much as I love the rest of the music, Oblivion and Morrowind's battle themes lacked intensity. "Watch the Skies" is incredible to hear when fighting dragons, though.

I'd say they're tied otherwise, though. They're all fairly different to match their settings. Skyrim's was much more Norse Viking-inspired, Oblivion's was more standard fantasy, etc.

I like Morrowind's theme. For exploring music, it's pretty much a tie with me between Morrowind and Oblivion.

For me MW but lets not pretend to objectivity. Most of us are going to choose our favourite or our first TES game (hey, I got to do both )

Skyrim with the Dragonborn DLC, which adds back several tracks from Morrowind. Going to Solstheim is like going home, with the familiar Morrowind exploration music.

Main theme: Morrowind

Overall: Oblivion

Probably Oblivion,exploration music sound like haven.

Personally, hands down I believe Skyrim (and its DLC) has the best soundtrack of the series. Of course, I prefer Morrowind's theme, Call of Magic, to any of the others. Skyrim's theme with Todd's "Barbarian Choir" is my least favorite of the last three, but it's still impressive.
