It would be interesting to be able to distinguish between "compliant" and "non-compliant" files in different directories. I use an external application to read and classify my MP3s. I only move my MP3s to the folder managed by this application when I am sure the tags are OK. I would like to be able to quickly move the validated files to my music library to give me time to process the remaining files with bliss. Another solution would be to be able to access an API to easily find compliant files and move them independently of non-compliant files.
