Full disclosure: I am not connected with puddletag or its developers in any way except loving their application.
In the process of getting my music library filenames more consistent, I looked at several tag editors.
Best one I saw for my purpose is pubbletag. It's got a spreadsheet-like view that shows all the tags for all the songs in a whole album (or directory).
Plus It's got functions including one that will rename files based on a user-configurable pattern from the tags. (or vice versa).
This is exactly what i needed to fix the hundreds of filenames in my music library,
If you need a tag editor check out puddletag. You can get it in Synaptic or with apt. It's working great for me!
