Fun.
My 1st birthday celebrated I Will Survive sung by the ferocious Gloria Gaynor.
My 18th birthday celebrated Wannabe by the Spice Girls.
Both of these songs are guilty pleasures for me.
What songs do you get?
Oh god… The Chipmunk Song by Alvin and the Chipmunks.
That’s a bit of ignorance that could’ve gone undisspelled. Really.
People got to be free - The Rascals was number one the day I was born.
I never had any psychic connection with the song.
Now, if Ball of Confusion came up…
Is that for US or UK?
Or just ask me…the guy who knows virtually everything about No.1 hits 
Mine was Bright Eyes by Art Garfunkel.Suits me
Day I was born: Night Fever, Bee Gees
18th Birthday: Always Be My Baby, Mariah Carey
21st Birthday: No Scrubs, TLC
On the day I was born:
A Big Hunk O’ Love by Elvis Presley
Thus spake the prophet.
On the day I was born, it was “All In The Game” by Tommy Edwards.
10th birthday: “Hey Jude” by The Beatles.
20th birthday: “Kiss You All Over” by Exile.
30th birthday: “Don’t Worry Be Happy” by Bobby McFerrin (ugh).
40th birthday: “I Don’t Want To Miss A Thing” by Aerosmith (never heard it).
Night Fever was #1 when I was born as well. You have a birthday coming up soon?
I’m so old, songs hadn’t been invented when I was born :eek:
Oh, wait, it was just that #1 song lists hadn’t been invented yet. Still…
When I became 18, though:
The Tears Of A Clown - Smokey Robinson & The Miracles
Talk about sheer perfundity.
Popstrology is the same, but take the concept a bit further, at least for USians.
I’m a Smokey Robinson & the Miracles (Tears of a Clown) born in the Year of the Jackson 5.
Could be worse-- it’s not my favorite Smokey song, but at least it’s not the Jackson 5 or something worse.
The Letter - The Box Tops
Not only did I learn that my birth song was “Thank You (Falettinme Be Mice Elf Agin)” by Sly & The Family Stone, but I also learned that was indeed how they spelled it.
I Want To Know What Love Is
Ugh.
“Let’s Stay Together” by Al Green.
Yes, as a matter of fact, I do take a tremendous amount of pride in the fact that mine was cool.
::bows::
(in GB, it was “Telegram Sam” by T. Rex. I have no idea what that is.)
That’s an amazing song, from “The Slider” LP, one of my all-time faves. It’s got the strangest lyrics, to wit:
Automatic shoes, automatic shoes
Give me 3D vision and the California blues…
but then an awful lot of Marc Bolan’s lyrics have really strange lyrics.
On the day I was born, Kiss You All Over by Exile was #1 on the US charts.
On my twenty-first birthday, it was Unpretty by TLC.
On my birthday it was Le Freak by Chic. On my 18th birthday it was Unbreak My Heart by Toni Braxton.
Meh, I could take or leave either song.
I did the US one.
I was born a year before they started keeping track.

US:
Zeroth birthday: “Hey Jude” by the Beatles
