Hi sveakul (sorry If I mis-spelled, your message disappears when I am preparing the reply) Thanks for the super fast response. 1. I'll try the procedure you mention 2. Sometimes I do the change within Musicbee, sometimes I use a 3rd party software for that. either way the problem can occur. Are there different solutions for the two options? 3. Sorry, I'm a newbie. What does it mean to "rescan"? How do I do that? (I assume that is the procedure you mentioned. If it involves something else, please clarify.) Many Thanks again !!
