[Etude]

I use setlists to keep track of my music by topic.  Disco, 80's, 70's, movies, Broadway, country, etc.

It occurs to me that it would be nice to be able to sort a playlist by most recently played.  So I could look at a setlist and say, "That's at the bottom of the list, guess I haven't played it for a while".

I concur. I have about half of my library in Musescore on a MacBook. I wrote a shell script to randomly select tunes to play. I keep a list of tunes along with the count of tunes played since the last time the list was reset (which occurs when the library changes or all tunes have been played). The latest selection gets moved to the end of the list and new tunes are only selected from the ones that haven’t been played. I ignore this script until I get tired of playing my favorites over and over. I’ve recently discovered some new favorites.
