Pretty good.
1.) Its pretty generic, so don't worry bout the Eberron label.
2.) Its similar to the D&D Soundtrack, I wouldn't be surprised if they are done by the same people.
3.) Its background music, unlike a movie soundtrack. Not alot of cresendos or action to the music. Its mostly atmosphere, as opposed to more traditional movie scores.
4.) I'll pick it up, I'm a sucker for D&D/Eberron stuff, and I LIKE the D&D soundtrack.
