I always think of stuff like Verdi when I think of operas, with the style of singing of the opera within an opera in Phantom. I don't know if there's another term for that? Classical opera? Like the stuff The Met puts on rather than Broadway. But I understand what you're saying!

I've never seen Les Mis. I grew up with Sound of Music because my mom loved it.

I find musicals a little odd because characters suddenly breaking into song is still very strange to me. I think operas make more sense to my brain because it's clearer the artform is that everything is a song, like an epic poem or something. But obviously I love Steven Universe so I can get used to it. Though one of my least favorite songs from the show was Mr. Greg which was probably the most musical like of all the songs!
