Sing Du Ring an meinem Finger after a few days.

Also sing Jingle Bells Jazz version for the delayed exam, and O del mio amato ben to regain my memories

Beethoven: Symphony 9

It is insulting, but for real, in the total of 1 hour 5 minutes and 31 seconds, with 4 movements, all people will only remember An die Freude from the last movement. That's the main character.

I don't think I would listen to Beethoven for a while.

(btw, Symphony 9 is the first symphony which includes choir)
