This sounds 'close', but I wasn't trying to delete, and I wasn't using the keyboard at all.

I was only using the mouse to insert/move a new entry, and somehow during the move process, two "showed up" as highlighted, and then BOOM... it locked up, crashed, and upon re-entry to the program all songs below that entry were duplicated with one song. Very strange.

I'm sure it will happen someday to someone else... just a matter of time. As a developer myself, I can say that this one will most likely be hard to find.
