Uhhhh I can be kind of a basic bitch sometimes. Wicked is high up there, So is In The Heights which also has an amazing movie adaptation by John Chu, Tick Tick Boom is definitely also high up there because of the movie, but my FAVORITE would absolutely be Falsettos. Absolutely beautiful time capsule of gay culture in the 70s and 80s, and a very real tragedy piece. Not to mention the music is all around wonderful
