The greatest Pop song yet written and recorded.

BTW as a footnote to the above, "White Christmas" as sung by Crosby is the biggest selling single of all time according to Guinness.  More interesting is that it was written by irving Berlin who is Jewish and did not celebrate Christmas per se and the talk show host who went on and on about it back when was Alan Berg...

I wish there were a way to upvote the submissions, since I agree with many of the submissions.

Thanks to whoever brought us the Father John Mundy song. I liked it a lot and want to listen to it, and some others, when I’m less busy than I am right now.

What a wonderful list we have contributed to here. It’s hard for me to pick a favorite song of all time, but previous posters have hit on a number of the ones I have thought of as "favorite" over the years (I don’t go for "best").

"Will You Love Me Tomorrow" is an early, pre-pubescent favorite by the Shirelles. I knew something lay ahead in the attraction/love department when I got a little older, and that song prepared me for the fact that it—whatever it was—mightn’t always go so well. The melody and the girls’ voices, well, I became a girl group fan whenever I started hearing that song, probably in 1963 on the Scott Muni show (77 WABC-AM).

Then came two of my other favorites, "Be My Baby" and "Then He Kissed Me," Phil Spector productions by the Ronettes and the Crystals. Courtesy of You Tube and my hard drives filled with songs, I still listen regularly to those two, as well as all of the songs I’m listing here.

Someone mentioned the Beach Boys having been declared uncool. I bought into that idea as an incipient hippie in 1966, and ended up not buying Pet Sounds until it was rereleased in 1974 on Brother Records (I had started my album collection with Surfer Girl and Surfin’ USA, and had bought every subsequent Beach Boys LP and 45). And I knew nothing of Smile until I bought the Good Vibrations box set in 1993. I had the singles that came from those albums, and have thought of "Heroes and Villains" as a favorite song of all time many a year.

I like "You Still Believe in Me" more than I like "God Only Knows" from Pet Sounds. Each time they sing "cry-y-y-y-y" with sixteen y’s is the clearest summons to musical nirvana I know of. Except when it’s the bum-de-bum-bum drum starting "Be My Baby." Or the horn and drum swirl that brings us to our feet as it opens Martha and the Vandella’s "Dancing in the Street."

Someone mentioned Cat Stevens. I liked him, though not as much as I’ve liked other artists. The song that sticks with me is "How Can I Tell You?", which someone used to play at me, hoping it would get me to fall in love with him. But it’s a beautiful song.

So many more: haven’t even touched Carly Simon ("You’re So Vain") or Linda Ronstadt, my all-time favorite singer ("Long, Long Time"). Or Joni Mitchell ("Rainy Night House"). Or Warren Zevon, especially "Desperados under the Eaves" from his first album.

Oh, and I always liked "12:30 (Young Girls Are Coming to the Canyon)" more than "California Dreaming." It’s what I’m going to listen to next, when I’m done with "How Can I Tell You?" The first line always gets me these days, as I used to live in New York City, and out my windows, I had a view of the Con Ed clock (which was not stuck at 12:30, but still).

When I think of the Best Pop Song ever written and recorded, I think of what song that will make a lasting impression on people of all ages, race and religion, and it must be a song can be sung universally. In my opinion, there is only one song that can do this, and that song is "Hey Jude" by the Beatles.
