Originally posted by: MeBeJediMight as well go to Neil's site to see what the details about a "muffled soundtrack" are. 
It's no secret. Last year, there was a bonus disc with the ROTS soundtrack at Target when the ROTS DVD was released. It was a collection of music from all 6 of the films. I don't have it with me here right now, but I distinctly remember the the Star Wars cues being mixed in the current Williams/Murphy aesthetic: drenched in reverb. It was especially noticable in "Imperial Attack" when compared to the SE album. Sadly, I think this may be a sign of things to come.
