I think what upnext is referring to is a singer database rather than a playlist. Using the search funtcion to look up a singer and add a previously sung song by that singer to the playlist, eliminating the need to keep a singers old songslips. This feature was suggested in the feature request section of the forum at some time in the past, though I don't recall MTU's response to it. Now that I've stopped lugging discs itwould be nice to get rid of the big box of envelopes as well

As for the songs showing as played about the only thing you can do is stop or skip before the song/file plays to the end
