Theres a lengthy review of the soundtrack for Casino Royale online and it includes excerpts of each of the tracks for you to listen to.

Over in the main article Ive listed all the track names so as not to give you any spoilers. Theres nothing amazingly spoiler-esque and if youve been following Casino Royale from the beginning youre going to know all about it, however just to be safe Ill leave them until the main article.

The soundtrack sounds strong and the review, over at Soundtrack.net, is certainly very detailed and positive. Heres an excerpt of what they say up front:

Returning to score this latest adventure is composer David Arnold, who has scored the past three James Bond films, Tomorrow Never Dies, The World is Not Enough and Die Another Day. While his previous films have leaned heavily on an orchestral/electronic fusion sound, Casino Royale focuses more on the orchestra, and uses electronics sparingly. Also - and interestingly enough - Monty Normans classic "James Bond Theme" is scarce, only showing up a couple of times over the course of the 75-minute album. This makes sense, since its not until the end that James Bond becomes "James Bond". Instead, Arnold utilizes a melody he wrote for the films song, "You Know My Name", which subtly hints at a precursor (with the ascending bass line) to the Bond theme. It should be noted, in a rather unique situation, that the soundtrack release does not include the song to the film

Its an excellent and very interesting review, and over the page you can read the track listing...
