Replacing iPodClassic with MediaDrive - Three key bugs to fix. Workaround with mp3tag

My situation is exactly the same as yours: size of the music content, need to get rid of iPad classic…but I can’t seem to get the music in the wmd in the right order. Only some of my music appears in “music” and therefore is classified by album, artist, etc. How did you do it? I would be extremely grateful if you could help me.
