30 Songs آپ Had No Idea Bruno Mars Wrote 

Bruno Mars’ list of writing credits reads like a hitmaker’s how-to guide. It’s kind of wild how talented he is, but it’s not particularly surprising — we’ve seen Mars out there, tearing it up on “Uptown Funk” (which he co-wrote with Mark Ronson and a handful of other talents), “Locked Out Of Heaven,” “Grenade” and all of his signature songs.

But what you don’t often see is Mars’ behind-the-scenes production and writing work, which can definitely be described as prolific. Along with Philip Lawrence and Ari Levine, the three make up The Smeezingtons, a powerhouse pop music writing team whose long list of credits needs its own Wikipedia page.

But to save you parceling through all that, we’ve highlighted 30 of them here — in honor of Mars’ 30th birthday.

So, happy birthday, Bruno! Keep cranking ’em out, and we promise we’ll keep listening.

Undeniably THE feel-good soul-pop hit of 2010, CeeLo’s “F–k You” was the fruitful partnership between Green, the Smeezingtons and Brody Brown. Still can’t get it out of my head, tbh.

Jay Z & Kanye West ft. Beyoncé: “Lift Off”

jam is, in fact, a true jam — co-written by Mars and a whole slew of talented songwriters, including Seal. Yes, that Seal.

Snoop Dogg ft. Wiz Khalifa & Bruno Mars: “Young, Wild & Free”

It’s probably too late, but the vid is little NSFW. Or maybe not. It’s hard to tell what’s SFW and NSFW these days.

Mars and Dr. Luke were only two of the mad scientists who helped craft this ’80s-sampling tune.

K’naan ft. Adam Levine: “Bang Bang (She Shot Me)”

a Bruno-patented banger with him on the hook. Adam’s pretty great, though.

Travie brought the raps, but Bruno sang the hook on this 2010 tune. And he might as well have, since he co-wrote it and all.

Mike Posner ft. Lil Wayne: “Bow Chicka Wow Wow”

Definitely some proto-“Gorilla” vibes in this one.

Major Lazer ft. Bruno Mars, 2 Chainz, Tyga & Mystic: “Bubble Butt”

Bruno had a hand in carving out this 2013 single from The Vamps’ debut, co-produced by Norwegian team Espionage.

Co-written by Mars and produced by Dr. Luke and Benny Blanco, this 2011 jam was destined for success from the get-go.

OK, so if Bruno sings on a song, there’s a really good chance he had a hand in writing and/or producing it. Just sayin’.

A collab between The Smeezingtons and The Jackie Boyz, Kingston’s 2010 track was also featured hilariously on the Disney Channel’s “The Suite Life On Deck.”

This one, produced by Mars and Stereotypes, is further proof of Mars’ dominance of the pop charts before he stepped out on his own as a full-fledged performer.

Brandy absolutely kills it here, but Bruno’s version is equally magnificent in its own right.

Matis + Smeezingtons = a veritable anthem that was used heavily during the 2010 FIFA World Cup. Because, obviously.

My personal vote for one of the absolute best songs on this list. Top five, easily. Top three, potentially.

This ’09 electropop hit might not be within Bruno’s typical genres of play, but the slinky verse melodies are pure Smeezingtons.

A sunny Beatles-esque melody with a driving, pulsating electronic beat — yep, the Smeezingtons definitely had a hand in this one.

Borderline unrecognizable as a Mars composition but still a hearty R&B jam. More like this please? Can Bruno’s third album be entirely electro-funk?

Bruno sang this Smeezingtons composition, too, but it ended up on Charice’s album

Bruno also penned “Better” from Wu’s previous album,

Bruno collabed with frequent partners The Jackie Boyz and Garibay for this dance-pop gem from Palmer’s second mixtape in 2011.

Justin Michael & Kemal: “Her World Goes On”

Bruno’s on this one, too, obviously. And he sounds damn good.

, this tune’s brass and steady backbeat could’ve definitely been a Bruno original on his debut album. Instead, Canadian singer Melanie Fiona released it on

An ode to “my very first white girl,” this 2013 song from Goodie Mob’s

album is adorned with horns and soul-inspired rhythms, just like we’ve come to expect from Bru (and Cee Lo, tbh).

Shontelle ft. Asher Roth: “DJ Made Me Do It”

Further proof — from Shontelle’s 2010

Beneath the bebop moon, beneath the mambo sun.
