I am not sure if this topic has been discussed so I apologise in advance. I am a huge fan of the Elder Scrolls music and the works of Jeremy Soule. Listening to some of the tracks from Morrowind and Oblivion will often bring a tear to my eye as I plunge into deep nostalgia and I love how Skyrim has incorporated elements of both the past titles in its soundtrack.

What I am really wondering is whether Jeremy Soule is working on the music for ESO and will we hear many of the old tracks from the previous games? Also each new TES has a new incarnation of the main theme, will that be completely different?

Of course I know there will be new music to grow to love (one can hope), but I would love to roam the land of Tamriel to some of the greatest game music composed, in a whole new adventure...

It hasn't been announced yet who is composing the main theme for ESO. There are speculations that it might be https://www.youtube.com/watch?v=tJc206skRDk as one of his music pieces for sure has appeared in an http://elderscrollsonline.com/en/media/videos/411 (the 9 min intro one). As far as we know, Jeremy Soule isn't doing the music for ESO (which is unfortunate). You can hear a bit of what we guess to be the main theme for ESO at the very end of http://www.bethblog.com/podcast/episode 17.

Most of the music of ESO is also apparently http://www.gameinformer.com/b/features/archive/2012/05/12/talking-about-the-music-of-the-elder-scrolls-online.aspx unless they have changed that.
