Billboard is working better than ever for my limited purposes. The only limitation is that I rarely listen to music but to audiobooks, with the Audiobook Reader program, which has advantages over the music player. Billboard never displays the name of the audiobook I am listening to.

Any idea how I can get Billboard to display the Audiobook Reader selection that is playing? Right now I am using

{song? ★ }{song-artist}{song?
☊ }{song-title}
