Looking at that screenshot above it looks like times aren't the issue, it's that it needs better matching with the filename = auto-tagger source.
For example, "forever in love" has an almost exact match (just one Capital letter out) with the auto-tagger source, but it doesn't match.
That doesn't seem right...
I know you've spent a lot of time on this so as Bond has said it's already better than it was, and if you don't improve it further, thank you anyway for the improvements thus far!
