Well I spent the time to figure out which files it was getting hung up
on. Apparently there were some files with damages headers or something
that would play fine in all audio players, and for the most part you
could read the ID3 tags, but they were damaged enough where other
applications couldn't update the ID3 tags which is some sort of
verification of Myth's scanning issues. Some of the files I was able
to "save" by clearing the tags in The Godfather and re-writing them, a
few did not take to that and will have to be re-ripped.

Now, it still sucks that MythMusic just "freezes" when it gets to
these tracks instead of just skipping past them and moving on, perhaps
even making a log of which files are "bad". But at least I was able to
move those files out of the music directory and get the scan to
finish.

Oh and looked through that filescanner.cpp file and have no idea where
to even start, so that whole idea is not going to happen on this end.
Though I'd be happy to send a couple of the bad files to anyone
interested in seeing why Myth doesn't like them.
