Dear all,
I handle my mp3 collection with the SONOS Android app. This supports tag composer which I did not set consequently (as it is no 'primary' tag) but which I have available as first substring (followed by ' ' blank) in the title. How can I convert this into 40,000+ mp3-files ?
tag title 'Mozart K620 Zauberfloete'
tag composer empty, requested
tag composer 'Mozart'
I expect... nothing easier than this for you experts 
A big problem for me, 'What's next ?' for you... unauthorized after Neil Armstrong.
Thanks and best regards, Bernd.
