That one part of a musical song that makes you ASCEND

What's that one part of a musical song that scratches your brain just right? That you have to rewind and play over and over? For me, it's...

-The ending of The Day Off in Sunday in the Park With George. TAKING THE DAY OFF SUNDAY!!!! AFTER THE DREARY WEEK IS DEAD!

-The climax of the Ragtime prologue. Where they all sing together so majestically. It melts and chills me EVERY TIME.
