Which is basically what I did: I would start the swamp track (just over 2 minutes) and the sea travel track (about 3 minutes).
In short, the best music—the kind that truly amazed me from the first listen (maybe it's not worse now, but it's just not the same)—was in Heroes 2!
And in the first one, I didn't even really hear the music. But the sound effects were super! Especially when a lot of ghosts die (when they surround the hydra from all sides, and you bite them ALL at once! My speakers were choking! :) )
