Thanks,
this is better than nothing.
Being a database (MS SQL) specialist and being able (not good as you) to write in C# I'll be happy only when I'll be able to edit the database!
But for now, having the albums in the right order and being able to modify the tags (mostly "Classique" instead of "Classical") in JRMC and then import the new metadata into Muso, I'm happy.
Muso now runs on a different machine where HQPlayer is so I can forget the problem of the GC I have signalled to you a long time ago.
