“Rockin’ Is Our Business,” the Treniers.
If you don’t already know, it sounds as if you may be describing Foreigner’s “Juke Box Hero.”
And my favorite song about rockin’ is Dio’s “We Rock.” \m/:mad:\m/
Y’all have failed to mention - Rockin’ Robin!
tweet tweet tweet!
I actually hate that song. My IRL name is Robin, and I have been teased with that my entire life.
Hot Rockin’ by Judas Priest
“You Can’t Kill Rock and Roll” by Ozzy gets an honorable mention about being a ballad about rockin’
Speaking of animal-themed rockin’, there’s also Crocodile Rock by Elton John.
My vote goes to:
We Will Rock You by Queen
For Those About To Rock by AC/DC
…and my contribution to the list:
**Cum On Feel The Noize ** [SIC] as covered by Quiet Riot.
Hey, I know it’s corny, but it’s awesome, and I was born the year it came out, alright? 
“I Dig Rock and Roll Music,” Peter, Paul and Mary.
What? “most rockinest?” Never mind.
“Rock Your Socks” - Tenacious D
“I Like to Rock” (well, I do…) by April Wine.
AC/DC: Long Way to the Top (If you Wanna Rock & Roll)
I think the song the OP is referring to is “Rocket” by Def Leppard.
American Hair Band by Tuff – nothing but rocking about the rockinest buncha rockers who ever rocked.
Somehow, we have neglected to list Rick Derringer’s smokin’ “Rock & Roll, Hoochie Koo”. There, I’ve taken care of it.
“Rock You Like a Hurricane” isn’t about rockin’. It’s about fuckin’. Otherwise the lyrics wouldn’t make sense: “So give her inches, and feed her well…”
As for pure rockin’ songs, I’d nominate “Rocking Chair Rock’n Roll Blues” by Elf.
You could say the same of MOST of the songs about “rockin’.” At the very least, most are double entendres.
“Rock and roll” started out as a euphemism, y’know.
Has to be “Tribute” by Tenacious D. A tribute to the GREATEST SONG IN THE WORLD. If that’s not rockin’, I don’t know what is.
Patton Oswalt does a routine about Damn Yankees (and other 80s HARD ROCKIN’ BANDS) and their ability to defy the laws of physics with their rockin’ that kills me.
Really? Over the MC5’s original version? I gotta give it to the MC5. Hearing that original opening in the live version is bone-chilling: "Right now…right now…right now it’s time to…kick out the jams, motherfckers!!!*
Oh, lord help us the day a cheesy rock song doesn’t make sense.
As mentioned in a recent thread, Don’t Try to Lay No Boogie-Woogie on the King of Rock-and-Roll.
(I started thinking of quite a few oldies that match the OP, but as I read on, just about every one of them was already mentioned.)
The Collins Kids - Rock Boppin’ Baby
Check out that kid on the double-necked guitar: http://www.youtube.com/watch?v=MxDT72GXuoI
(OK, technically that song doesn’t rock that hard, but watch some of their other stuff- that kid kicks ass on the guitar.)
