So, how much music is missing? Either there's a lot of unused/alternate cues or we're getting the original OST too. I mainly recall the music being quite sombre and subdued, until some lively stuff near the end.
Hope this is better than the 2-disc releases of Howard's Dreamcatcher and Outbreak, both of which I found to be colossal snoozes. The initial half-hour CD was one of the first Howard scores I ever owned, and I remember liking it a lot.
