So that's why renaming the file did not automatically change the song title. However, I'm not opposed to changing the logic such that, if a song has a single file, that file is renamed and the current title matched the automatically generated title from the previous file name, that I update the song title to match the new file name. If any users don't want this behavior, please post in this thread.

Hi Mike,
I'm in 2 minds about this.  Perhaps a checkbox might be a useful alternative?

For myself, because of the way I name pdf's* when creating charts for a couple of the bands I'm in, I think I'd prefer if the current behaviour didn't change.  That said, I can also see the convenience for the use case under discussion.

* I include versioning info in the filename if a chart is updated/corrected.
E.G.
"Moonglow-Trom.pdf" might become "Moonglow-V1a-Trom.pdf" if there was a typo or some other correction made to the pdf.  
Under these conditions I'd want the entry in the songlist to remain "Moonglow-Trom".
Of course, I can also see the benefits of having versioning info in the songlist entry...
