Sometime members are not posting a single file to be listened to, but a group of tracks, as EP or album.
In this case it would be convenient to include a playlist file in the package to be downloaded.
This would ensure a playing back in the right order, and with the right transition.
A basic form of the .m3u format already can achieve this : an ascii file with a list of the tracks in the directory.
If the tracks are already in the right file-manager order, this list can be made with the command :
dir *.formatname /b > albumname.m3u
