So, when I edit my playlists I usually edit the amount of each track I want on excel, then save them to a notepad file saved .m3u
Then I use File > Playlists > Import Playlists... to add that file to MusicBee
The import works fine and tracks are added correctly, just not at the count that I chose like it used to be, but just one of each instead
this is what it looks like on notepad, it adds to the amount of 9653 tracks
and this is what it looks like after imported into musicbee with only one of each track
thanks a lot
