Yep, all albums and songs are listed in Kagu.

Just to be certain of the viability of what I'm experiencing, I've once again gone into xterm, copied my back-up playlist into /.kagu/playlist.m3u, double-checked to make certain that /.kagu/playlist.m3u held the duplicate of my backed-up playlist (which it did), then booted up Kagu, found nothing, went back in xterm to /.kagu/playlist.m3u -- and it again was empty. Booting up Kagu is obviously erasing the playlist.m3u file. Any further thoughts. Regards, Jim
