Are you sure about the format???? m3u = playlist format

m3u doesn't actually contain any music. It is simply a document that lists a list of songs & pointers as to their location so the player knows where they can be found. But once an m3u file is moved away or the songs are moved away, then the m3u file won't work. I'll correct that, an m3u file can be utilised my many players, but all the original songs must be in the original location or directory path that they were when the m33u file was created. Many audio players can save playlists as m3u.
