I was a long time user of MM4 and used the Advanced Duplicate script a lot to copy metadata (including ratings and playlist info) when I re-ripped CD's at a higher bitrate. I just found out that the script does not work with MM5. Is there another to do the same thing for MM5 or do I need to migrate back to MM4?

It sounds like you may want to replace files with newer copies, this can, including on Playlists: https://www.mediamonkey.com/forum/viewtopic.php?t=13000

Otherwise, you can use Auto-Organize Files to Copy files based on tags.

I have been going through my music library (5500 songs) to convert the WMAs to MP3.
Everything under 128 kbps I have replaced with 192 kbps versions rather than converting.
So I have a few hundred songs that I need to copy to the existing folders: Artist/Album, or just Artist (if no album) in my music library.
I know Mediamonkey and other software (Amok Playlist Copy) can copy files from a playlist to a [i]new[/i] folder structure.
But this won't help me. As then I will just have two sets of folders.

Any ideas?
