In fairness, I’m not sure “Brickhouse” fits either since he does give out the measurements 36-24-36. Just an observation.
Does “Poison” by Bel Biv Devoe work?
No list of songs about large women is complete without “Roberta” by the Reverend Billy C. Wirtz. You just have to hear it to believe it.
Roberta, Roberta, get your big legs offa me.
I always liked “Big-Boned Gal” from k. d. lang’s Absolute Torch and Twang album:
she was a big boned gal
from southern alberta
you just couldn’t call her small
and you can bet every saturday night
she’d be heading for the legion hall
if you can get hold of some old reggae, try ‘Fatty fatty’, by The Heptones.

the first stanza…
*
I need a fat girl, fat girl
(fat girl tonight)
I need a very, very fat girl
(fat girl tonight)
I’m in the mood, the mood
(I’m in the mood)
I need some food, some food
(I need some food)
I’m feeling rude, so rude
(I’m feeling rude) *
I still think The Commodore’s “Brickhouse” oughta count, the sentiment fits right in there, even if the measurements don’t.
It’s a reach, but what about Hall & Oates’ “All American Girl” maybe?
“She’s got a double bubble with a bossanova back
She’s a real hot pepper and I like it like that”
That makes me giggle. 
Now I’m hungry for french bread, mmm.
Right, but Joe Tex’s song “Skinny Legs and All” is a song that’s about how no one wants a girl with skinny legs.
I’d throw out Laura Love’s “Mahbootay” which is a funky ode to her big butt:
My booty
my big ol’ booty
I take it shopping
I buy it presents
I clothe it with trousers
I feed it with peanut butter
I watch it growing
It gives me pleasure
Worship it
I don’t know about that. The woman is out at the club gettin’ down and definitely not afraid to go after any man she wants. That has a certain hotness about it even if Mr. Tex doesn’t think so.
Bob & Tom (otherwise useless morning DJ types) have a song called ‘More Cushion, less pushin’ in mock Dean and Jerry voices that may amuse. It certainly fits the criteria.
Has anyone suggested one of the many versions of ‘Love Handles’?
What, no love for “Rumpshaker”?
“Big Ole Butt” by Mr. James Todd Smith, aka LL Cool J
Unskinny Bop by Poison.
I uh… I like… uh… Even at my biggest, I really liked… even though it doesn’t necessarily apply… it made me die laughing… um… but maybe it’s just me.
Hotdog in a Hallway - NOFX?
“She’ll have another piece of pie
She’ll have a double reuben rye
She works hard at eating well
That’s why I love her.”
I think it’s cute!
“Big Fat Funky Booty” by the Spin Doctors is a good one.
“Baby Fat” - De La Soul. Hot song. I loved the video for this song which features a queue of girls outside a nightclub and the doorman leaning over a bunch of thin girls to wave to the, ahem, larger ladies at the back to come to the front of the queue.
In Skinny Women by the North Mississippi All-Stars, the singers express their dislike for skinny women because “meat don’t shake on her bone”
A nice pairing would be with Savoy Brown’s Meat Shakin’ Woman
Etta James’ Hawg For Ya might qualify
The Trailer Park Troubadors Skinny Women Ain’t Hip
