Hi,

to delete unsupported tags in .mp3: Ctrl-X -\> Ctrl-V is a great workaround.  
But on my Mac I have 90% .m4a files.

And unfortunately this doesn't work for .m4a files. Unsupported tags remain in the file.  
To be more precise, there is still information in the file, but via exiftool I don't see any tags or anything.  
But the information is still in the file. Source for the information: NI Traktor Pro

Any ideas how I can delete such informations?
