Are you talking about the scrolling message that shows the list of singers? If you are, I think 10 is good enough. I personally only show 3 sometimes 4 singers.
more than 10 is a lot, (though i don't see why it would be out of the question to make it optional, we can already pick a number) but i am with you guys, i show 5 (~20 minutes... or a good smoke and pee break)
