BOM Musical

I’m going to New York for a Work trip in a couple weeks and going to watch the book of Mormon musical on Broadway. Should I listen to the music beforehand or let it be a surprise when I get there? I have a good time making fun of my younger self and I’m not worried about having some kind of drama response so I’m asking more with the lens of being surprised or enjoying it because I already know the songs. For those of you who are passionate about musicals or have seen it, which do you recommend?
