In a live music situation you have to keep things moving so the dancers don't leave the dance floor. I think Jukebox would benefit from a feature that appears in just about every DJ software.

They all have 2 windows: one of them is the song that's playing and the other one is the next song. Typically the next song is set to fade in while the current song is fading out, so there is never a time when the current song is over and nothing is playing.

They also provide a way to synchronize the tempo so the next song literally "doesn't miss a beat". The two song lists are typically sorted by tempo to make this easier

Obviously there are times when you need the music to stop in order to make announcements, but it would be nice if the option to keep the music playing could be toggled on and off with a USB footswitch.

If you'd rather not mess with Jukebox, an alternative idea might be to make a full-blown DJ program that loads SEQ files in addition to other audio file types. The music market has already transitioned to DJs and such a product would make the rest of your suite more useful to that demographic.
