Oml, I absolutely ADORE musicals! They're so awesome! I'm happy you've already listened to a few like Hamilton and Heathers.
You should definitely expand your horizons and listen to more awesome musicals! For example, I suggest you listen to:
Be More Chill (NUMBER ONE RECOMMENDATION!)
Dear Evan Hansen
The Lightning Thief
And if you like Spongebob or just want pure art..
Spongebob: The Musical XD
