Comment 2 for bug 1110164

I thik it is up to the user to choose if he wants access to up-to-date playlists quickly OR if he wants fix album-like playlists once loaded by import! The DJ knows about the possibility to get the same songs via two ways and will be able to handle that!
No, the big advantage is the possibility to have two methods to access to song sources. To individually and independantly load a song to a playlist without the duty of a carefully or systematic collection via the Mixxx database.

See also VirtualDJ. They did the same and I think it is consequent.

It is easy for the Mixx explorer to resolve m3u files and show it in the track lists, isn't it?
