WBUR–Boston's Julie Wittes Schack says Joni Mitchell's "A Case of You" tops the list:
[N]ow, nearly 50 years after it was released on “Blue,” one of the best singer/songwriter albums of all time, I can still confidently assert that “A Case of You” is one of the best love songs ever written. The quantitative evidence of that can be found in the fact that there are over 300 known cover versions of it; 300 artists who found something in its distinctive melody or conversational lyrics that they felt they could make their own.
But it’s not the number of versions that makes this song so enduring. It speaks to each new generation of singers because of the feeling it evoked in me, even when I was a moony teenager, driven by inchoate longings, knowing that there were insights still well beyond my reach. This is a love song by and about grown-ups.
There’s no giddiness here. Unlike practically every pop song that came before it, in this one, love is not an intoxicant. Quite the opposite, in fact:
I could drink a case of you darling and I would
Still be on my feet
Oh I would still be on my feet
Some understand those lines to say that she can’t get too much of her lover (variously speculated to be Graham Nash or Leonard Cohen). But what I hear all these years later — and the interpretation I prefer — is that with the clarity generated by time and age, she can drink him in, savor him and still be sober enough to clearly see him.
I got Blue in 2000, and I agree it's one of the best albums ever. As I'm wending my way through my CD collection I've got a ways to go before hitting it. But I'm looking forward to hearing it again.
