I rather like Cabaret, Rocky Horror and Jesus Christ Superstar just for the music alone (the acting and design are fantastic too) Hedwig is an amazing experience. I saw a stage production but the film was much better.
Never saw or heard about Hedwig. I also have never seen Rocky Horror. I have seen Cabaret and Jesus Christ Superstar. I remember watching a local production of Cabaret. The actor playing the Nazi singing the last line at the end of act 1 “Tomorrow Belongs to me” was quite chilling. I sometimes watch in the movie version of Jesus Christ Superstar at Easter time. It is not quite my style of music, but I like it.
