The physical soundtrack comes on a whopping 4 CDs and there's a lot of music here: 53 tracks, although one of the tracks is a 40 minute long track of ambient music/sound effects so I didn't really listen to the last disc. No surprises that he was recruited again to do the soundtrack for Skyrim.
He's created classic soundtracks for games such as Star Wars: Knights of the Old Republic, Guild Wars and of course the previous two Elder Scrolls games, Morrowind and Oblivion. Since I ordered early too I actually managed to get Jeremy Soule's signature on it too (hopefully it'll be worth something someday :)).
For those who regularly read my blog, you would know I ordered in the special physical edition of the Skyrim soundtrack from directsong.
