“Mandy” - Barry Manilow
“Cracklin’ Rosie” - Neil Diamond
“It’s Not Unusual” - Tom Jones
This thread is all about Captain & Tennille. Specifically, “Do That To Me One More Time,” “Love Will Keep Us Together,” and “Muskrat Love.”
Where, I say, WHERE is the Meatloaf? We must have Two Out of Three Ain’t Bad, I’d Do Anything For Love, and the mother of all overwrought ballads, Paradise By the Dashboard Light (which I personally think is hysterical and I can’t listen to without laughing and singing the whole damn thing).
Also: Beth by Kiss and Keep on Lovin’ You by REO Speedwagon.
Open Arms by Journey.
It’s Rainin’ Men!
There are all kinds of cheese. You needs some Sensitive Seventies Singer-Songwriter cheese.
-
Cat Stevens: “Peace Train” or “Moon Shadow” or “Morning Has Broken” (it was always pathetic when nuns would try to play this one at Mass, thinking it showed how hip and cool they were!)
-
John Denver: “Sunshine on My Shoulders” or “Thank God I’m a Country Boy” (I actually love a lot of John’s music, but these two are a bit over the line)
-
Lobo: “Me and You and a Dog Named Boo” or “I’d Love You to Want Me.”
-
Henry Gross’ “Shannon” (a sad song about a lost doggie)
There’s also
Clint Holmes’ “Playground in My Mind”
Michael Jackson’s “Ben”
“I’ve Never Been to Me” by Charlene would fit right in here.
Do You Believe in Magic? by the Lovin’ Spoonfuls
If you’re going to include “Country Boy”, then you must also include “Grandma’s Feather Bed.” 
Which reminds me of Michael Martin Murphey’s “Wildfire”, a sad song about a lost horse (which, for some reason, was imperiled by a “killing frost”…what, is the horse actually a petunia??)
What’s that Taco song? Oh yeah! Puttin’ on the Ritz. Your mix must have this. And possibly Afternoon Delight, too, although I can’t stomach that song.
“The Final Countdown” by Europe
“Billy, Don’t be a Hero” by Paper Lace
“Honey” by Bobby Goldsboro
“I Can See Clearly Now” by Johnny Nash
pure cheesy goodness
You simply must include ABBA. “Dancing Queen”, “SOS”, “Fernando”.
Eats_Crayons, do you want this playlist to be a pleasant listening experience? Many of the songs listed are of the Knitting-needles-to-the-ears variety. But guess that is a matter of opinion.
The Carpenters had many delicious hits au gratin: “Close to You”, “Superstar”…
Wow, now that’s cheesy. Puts my Neil Diamond suggestion to shame!
Awesome mix.
All that’s missing is some Oran Juice Jones… because how cheesy can you be if you don’t have The Rain. (Bonus - the recent YouTube comments on this video are downright hilarious)
Oh, that’s what that line is! Dude!
BTW, whenever these songs come on the car radio I pray there’s no axe murderer hiding in the back and not for fear of death but for fear of shame. It still doesn’t stop me from singing along though.
And The Night Chicago Died.
Lord help me, I love Kung Fu Fighting. (HUH!)
And Rock the Boat. And Midnight at the Oasis. 
Peter Cetera Glory of Love should fit on the OP’s list since she mentioned Peter Cetera era Chicago. This is one of the cheesiest songs that I can recall from that era.
I was just reminded of Mr Mister’s song “Broken Wings” and Starship’s “We built this City”.
“One Night Love Affair” by Bryan Adams. As featured in “Real Genius!” So double plus for having been featured in a seminal 80s flick. “Summer of '69” is maybe a hair cheesier, but reasonable minds can differ.
"Don’t You Forget About Me (theme from “The Breakfast Club.”)
“Hurt So Good” by John Cougar Mellencamp
