I saw it on a documentary, a. Someone said it. He said, "The best pop song of all time is The Ronettes 'Be My Baby'." Now, I can't remember who he was, but he was on a documentary so you can't argue with that.
He's probably right inasmuch as 'the best' of something subjective can be defined, as well.
You don't move your hips and have a grope at the missus when your hear Let's Get It On?
You can't see the alleyway when Dorothy Moore sings Dark End Of The Street?
You don't tap your foot when you hear You Can't Hurry Love?
You don't hear violins when Smokey sings?*
