Proven again, rescoring helps the movies so much.
Also, BTW I have been trying to get back at this with several new methods of music/SFX removal that I've come up with myself. They're really experimental, but if I can figure out how to execute them just right, I may be able to isolate the vocals perfectly.
I'm repairing my computer this week, so I'll get to work on it soon, and hopefully I'll get much better results.
