in your opinion - what is the best song ever recorded?

@SecureOwl there's so many great songs it's hard to narrow it down to one for all time.
Roberta Flack's Compared to What? has struck a chord with me recently. The song was recorded in 1968 but damn if it isnt eeriely prescient when viewed in the light of the current state of things.

A little harder hitting is The Dandy Warhols / Slash tune I'd like to Help you with Your Problem
