If you do a tweak by artist, and get the "no matching artist found" message then the current song cannot be changed, pressing the skip buttons on the front panel causes the title information to change, but it doesn't change what is playing. Also when the playing song reaches the end you just get silence, even though it is not the end of the playlist.
