Using filenames as your titles
If you want to display the file name as the title for your files, then you can simply adjust the Display Titles for your Mezzmo library.
Go to the Options dialog (General page) and click the Display Titles button.
On the Display Titles dialog, click Presets and select %FILENAME% for all the types of files you want to see file names as your titles.
Click OK to save your changes and your files should now be listed using file names.
