Did I see correctly that if you don’t make the shots during a song, the booing off the stage doesn’t just end the song but has you drain? If so, that’s likely why every song is a multiball. It does allow people to play longer and hear more of the song. The game then becomes more of a a Guitar Hero / Rock Band type game where you just try to stay alive. And it focuses on the concert experience with the light show and everything. So, it does seem like a design choice. It might not be for everyone, but it is different in terms of how most pins are played.
