Wait, wait - what are we talking about here, making an isolated score (MUSIC ONLY) track, or using ABC's audiophile soundtrack to make the music more prominent in the mix?
The use of the words "attenuate" and "overlay" are what's confusing me, I think.
If you're talking about an isolated score, then hell yeah, go for it, that'd be awesome!
If you're talking about making the music more prominent in the mix ... why?
