MP3 finger

MP3 Fingerprinting is an absolute must for me - freedb.org did not match any of the hundreds I tried.
User interface not intuitive but is usable once a person figures out what is what and what order things need to be done in.
I have 43000+ songs. The scan never completed after 2 hours. If I selected individual directories, but it became too tedious and I gave up.
Not enough incentive to continue testing without a better ability to check/validate MP3 tags.
