There used to be operas written for soprano castrati. Pretty much nobody alive can sing them.

'I Believe in a Thing Called Love' by the Darkness. I karaokeyed the shit out of that bitch when it first came out 3 or 4x. Now, I guess my voice dropped more since bc I tried to sing along when it was on the radio recently and came nowhere near being able to hit those high notes.

"More Than A Feeling" by Boston.

(Especially if the singer is also playing guitar at the same time).
