This does not look like the title to me.  
This looks like the filename.  
Check which data you already have in the tag fields. If they are empty or filled only with parts of the data that is visible in the filenames, then first import the data from the unstructured filename into the structured tag fields.

From there onwards, you can sort, filter, rename the files and see whether you really detect duplicates in that way.

> Can MP3TAG be used to identify duplicate files in different sub-directories if a listing is done from the top level Music directory? If not, this would be a great feature that would help to further cleanup and organize a music library by matching all tags in duplicated files and would attract many DJs like me. It would be worth the cost. DJ Blade Sparx
