Awesome, thanks! It took a little while, but I think it did the trick. Looks like it couldn't handle files that didn't have an album tag, though. Luckily those don't make up much of my library. ;)
edit: The delete blacklisted files seems like it just deletes everything. I got rid of every text file in the Saver2 directory and its subfolders, including the music save directory. Then I opened sproxy with the delete blacklisted files option enabled, and it wanted to delete everything in my music folder.
Guess I'll just hold off on trying to use this feature until it's worked on a bit more. Still, though, thanks for all the hard work and the saving music stuff works great.
