I like every single Carly Simon song I've ever heard

Actually, if you're the intended target, only 1 and 4 apply. Change that to three out of the four possibilities reflect badly on everyone who's ever heard the song. Most of us--me for sure--are safe with 3. For Warren Beatty and Mick Jagger and such, much trickier.

great stuff

you reckon there's more than one you in play? since it's the same word, I'd assume it refers to same subject throughout ("you walked..." "you're so vain" "don't you?") and the song can only be about you

leaving the question: who are you? two possible answers:

1) you're warren beatty or someone else intimately familiar with carly simon - this song may be about you, and you probably think it is

2) you don't know carly simon personally, so this song isn't specifically about you - but the meaning of the song might apply to you too; if you think it does, it does

I feel like it's a very important issue in 2015

carly simon and her publisher sure hope so!

I've always wondered if "You're So Vain" isn't about any man in particular—even if there are references to specific guys (i.e. Beatty)—but all men.
