10. Doc Pomus & Mort Shuman. This virtuosic Brill Building duo was highly influenced by the blues; they collaborated with Phil Spector and Lieber & Stoller on some truly high profile hits in the 1950s and '60s. Independent of one another, they wrote hits. But their biggest hits, such as "This Magic Moment" by the Drifters and Elvis' "Viva Las Vegas," were written together.
9. Desmond Child. After a failed attempt to make it as a singer in his own right, Child went behind the scenes -- and suddenly began cranking out the hits at an astounding pace. Child wrote many of the most recognizable hits of the '80s and '90s, including Aerosmith's "Crazy" and "Dude Looks Like a Lady," Ricky Martin's "Livin' La Vida Loca," Sisqo's "Thong Song", Alice Cooper's "Poison," and many of Bon Jovi's most famous tunes (including "Livin' On a Prayer," "You Give Love a Bad Name," and "Bad Medicine").
8. Barry & Greenwich. Another husband-and-wife duo that sprang from the Brill Building, Jeff Barry and Ellie Greenwich co-wrote an astonishing number of hits, including "Be My Baby" (The Ronettes), "Da Doo Ron Ron" (The Crystals), and "Do Wah Diddy" (Manfred Mann). Barry & Greenwich later partnered with a young songwriter they discovered during his own years in the Brill Building -- some a guy named Neil Diamond. Together, Greenwich, Barry and Diamond composed hits like "Kentucky Woman" that spurred on Diamond's burgeoning career.
7. Stargate. That flawless production and catchy hook on Beyonce's "Irreplaceable" comes courtesy of this Swedish duo (government names Mikkel Storleer Eriksen and Tor Erik Hermansen). In the five years since "Irreplaceable" topped the charts, Stargate have written and produced a bunch of hits for Rihanna, including "Rude Boy," "Take A Bow," "Only Girl In the World," and "What's My Name," as well as taking over production duties on Katy Perry's "Firework."
6. Boyce & Hart. This Don Kirshner-backed duo tried to make it as performers,. But they weren't young enough, cute enough and charismatic enough for people to pay attention. Instead, these brilliant songwriters moved behind the scenes, penning, most notably songs for a quartet of young, cute, and charismatic boys called The Monkees.
