I think it's the best of Soule's themes yet - of course most of the original melody originates from Morrowind, so I voted it as "not as good as". Polls don't provide reliable demographics.
In the YouTube video of Todd Howard's announcement of the trailer, I heard background music that sounded pretty good - assuming it's for Skyrim as well, I think the game's soundtrack will be better than Oblivion's, at the very least.
