Hi,
I think it's useful if mp3wrap could make mp3 according to a standard m3u playlist file. I could work around it using excel to convert to m3u to a string listing the mp3's in order to be joined, but i thought it's useful to have the m3u option.
Thanks
In case you are still looking, you can write a batch file to take the playlist and create a list of files in a variable, to then use with MP3wrap to create a file from.
