Baker Street by Gerry Rafferty
Birdland by Weather Report
Just the Way You Are by Billy Joel
These songs and a lot of the others listed here are part of the soundtrack of the trips we took into Cincinnati circa '77 to visit my grandmother. Though Baker Street actually couldn’t be, it’s still earned its place there for some mishmashed childhood-memory reason. The sax part haunted me till I heard it again years later.
Nothing From Nothing by Billy Preston
Will It Go Round in Circles by Billy Preston
WLS was my lifeline to the outside world. I remember listening to it late Saturday nights in my farm house in northern Missouri.
Oh come on, no mention of “My Sharona”??!!
Psst! Post #14!
Well it’s not at all what the OP was thinking, but it’s what the OP made me think of and it was 70’s radio. The first thing that popped into my head was Larry Lujack’s Animal Stories. Gosh I thought they were funny when I was 8. Probably they aren’t actually so funny.
“School’s Out” by Alice Cooper
I listen to the new sound of 13-Q! 
Gotta put in a plug for my old Top 40 AM friend, 1050 CHUM, in Toronto, and the hits they were playing in September 1972:
Mac Davis, “Baby, Don’t Get Hooked on Me”
Donny Osmond, “Lonely Boy”
Bill Withers, “Lean on Me”
Gilbert O’Sullivan, “Alone Again (Naturally)” though this was bigger in the early summer
…and many more.
And although it was some years later, a shout out to the Brothers Johnson for “Strawberry Letter 23” in 1977.
Here are some more obscure Those '70s Singles

I was young and obsessed with sex. Now, three and a half decades later, I’m middle-aged and obsessed with sex.
A few more:
Muskrat Love - Captain and Tennille
Baby I a Want you - Bread
The Night Chicago Died - Paper Lace
Hi there! These should bring back memories.
“Werewolves of London” wasn’t exactly a monster hit, didn’t quite crack the top-20, but I have a fond memory of hearing it on WLS. I was out with one of my sisters in April of '78 and she was driving us home; “Werewolves” came on the radio and we started howling along.
Well, technically it was a ‘monster’ hit. 
Oh yeah, I just remembered Billy, Don’t be a Hero and The Night Chicago Died!!
The days of AM radio being played at the public swimming pool over the speakers…nothing quite like it these days.
The 70s also gave us two more contenders for “Worst. Song. Ever.”–Rocky by Austin Roberts and Run Joey Run by David Geddes. With dreck like that dominating the airwaves in the mid-70s, is it any wonder disco was able to get a foothold?
Funny this subject should come up. I’m at work right now listening to the 70s channel on XM, as is my habit most Fridays. Just this morning, I’ve heard:
Fooled Around and Fell in Love by Elvin Bishop
The Boys Are Back In Town by Thin Lizzy
Little Willy by Sweet
Sing a Song by Earth, Wind & Fire
Right Place, Wrong Time by Dr. John
Sad Eyes by Robert John
Long Train Running by The Doobie Brothers
…and a special mention for Imagine by John Lennon–the very last song played on 77 WABC before they went all-talk–the end of a radio era.
Night Moves by Bob Seger
Hooked on a Feeling by **Blue Swede **(oogachakaoogaoogaoogachaka!)

Rock On by David Essex
Magnet and Steel by Walter Egan
Sentimental Lady by Bob Welch
Here in Quebec, a perennial also-ran French-language singer named Sylvain Cossette released an album called 70s, in which he sings his favorite English-language tunes from that decade. For the most part, he does surprisingly good interpretations, and he does a bang-on Freddy Mercury, especially in Somebody to Love. Anyway, the album and Cossette’s career have shot through the roof (comparatively speaking ;-). Here’s his selection:
More Than a Feeling
Rocket Man
Carry on Wayward Son
Somebody to Love
Cold as Ice
I’m Not in Love
I want You to Want Me
Stuck in the Middle With You
Rock’N Me
Jealous Guy
Angie
We Are the Champions
Let it Be
Moonshadow
Don’t blame me if any of these are slightly outside the 70s. I didn’t pick 'em…
S-A T-U-R D-A-Y NIGHT! – Bay City Rollers (My little 7th grade girlfriend’s favorite band)
Candy Man – Sammy Davis Jr.
D’yer Mak’er – Led Zeppelin (Over the P.A. at the hockey rink)
Beach Baby – First Class
Shannon – Henry Gross
The Wreck of the Edmund Fitzgerald – Gordon Lightfoot (The public swimming pool!)
Did anybody mention “Heart of Glass” by Blondie yet? It should be there.
“Video Killed the Radio Star” by the Buggles (normally associated with the 80s, but it was definitely a late 70s hit.)
“Come Sail Away” – Styx.
“Staying Alive” - the Bee Gees.
And as much as I’ve always hated the song, “Seasons In the Sun” by whatsisiname was an undeniable hit.
