I had a chance to speak with Chance Thomas.
This bonus soundtrack is pretty much a re-issue of the Shadows of Angmar with some tracks from Moria tacked on at the end.
A full Moria soundtrack exists on some extra that came with the North American release of Moria, called the "Lord of the Rings Online Music & Art Collection." It's an artbook with a 17-track CD (music from Chance Thomas and Stephen DiGregorio), all music from the Moria expansion.
Review will be up on
OSV in the near future.
