Actually, I was hoping to find a Creative Commons music with a space theme that 
would play under the credits and the speed would automatically adjust to it.

Just tried some tracks. Amazing how much perception differs when listening to 
music. Credits already seem to be a little bit faster :)

What exactly are you looking for? Some quiet, slow space track or the 
orchestrated space theme type? Both fits to IG imo. Ingame music is more like 
electronic space music while the cutscenes include orchestrated tracks (which 
sound surprisingly great btw...any idea how a small developer like DD could get 
orchestrated music?)

Tamas Kreiner did a great job back then, but I think everything was done with 
MIDI. It's hard to tell the right music parameters, We need to listen to many 
alternatives to decide.

The music of the cutscenes definitely wasn't done using MIDI...I'd bet one of 
my ears on that. But your right. Kreiner did a great job.

Just did a quick check. Some parts are midi in the cutscenes ;) Guess he used 
som eorchestrated samples here and there.
