Can't answer otherwise than "to each his own". But for also - also depends on when I'm planning on seeing the show. Just saw Hamilton on stage this past Friday (finally . . .). Sure as hell wasn't going to wait to listen! Also - depends on show. There are many shows where you pretty much know the plot or knowing the plot is almost irrelevant. More likely to listen to those. Although I did listen to Next to Normal because I didn't see that for far too long, that's a perfect example of a show I'd say DO NOT LISTEN!
