When doing playlist sync to multiple folders the playlist number is always included in the file name with no way to disable this behavior as far as I can tell from this post
If you're syncing each playlist to its own folder, you will always get the playlist number at the beginning. You'd need t request and change on the wishlist
This seems like unnecessary bloat to the file name given that the .m3u playlist file will already include the playlist order (and also means I have to reupload all my songs to my phone :/). A tickbox option in the sync settings would be super awesome!
