Alan,

I usually use Winamp, but experimented a bit with Musicmatch and found that in one respect it worked much better: Winamp has an irritating "feature" in that it creates a useless .m3u name (like 4tyh.m3u) when any playlist is created, despite giving it a sensible display name.
I am not sure what the "proper" way to create playlists is. They are really just a text shell with the location of the required files inside. I am not sure (being a cabinet maker, not an IT guru!) if there could be another way? I resolved that I must always create playlists on the PC that serves the music. That way, the absolute nature of the path always hits the right spot, even if music is kept in various directories.
