Favorite Song Produced By Pharrell – Readers Poll

Pharrell Williams is one man with an array of talents. Not only has he made a name for himself as a member of N.E.R.D. and as a solo artist, but he's also a big deal behind the scenes, as he's had a hand in the production of a wide variety of chart-topping hits, most recently hitting the studio with the likes of Miley Cyrus and Tyler, the Creator.

In celebration of the hit maker's 40th birthday today, April 5, we've narrowed down his vast production discography to 20 of our favorite tracks, and we want to which you like best! Is it one of his hip-hop hits, like 'Drop It Like It's Hot,' or maybe one of his many pop chart-toppers, like 'I'm a Slave 4 U'?

Pharrell's actually been in the production biz since the late '90s, and he had his first hit in 1999 with ODB's 'Got Your Money,' featuring Kelis. He lent his studio skills to a string of successful hip-hop tracks after that, including 'I Just Wanna Love U (Give It 2 Me)' by Jay-Z, 'Shake Ya A--' by Mystikal, his own group N.E.R.D's 'Lapdance,' and Fabolous' cat-call anthem 'Young'n (Holla Back).'

He then took a turn towards the Top 40 in 2001, producing the sexed-up, Britney Spears classic 'I'm a Slave 4 U.' That same year, he turned out Nelly's No. 1 summer jam 'Hot in Herre,' and not even a year later, was cranking out the beats for 'N Sync's last big hit, 'Girlfriend,' as well as Beyonce's funky 'Austin Powers' track 'Work It Out.'

Pharrell also lent his keen ears to Usher for 'U Don't Have to Call,' Justin Timberlake for 'Rock Your Body' (as well as a number of other tunes), and Kelis' seductive 'Milkshake.' He also helped out his buddy Snoop Dogg with production and featured vocals on 'Drop It Like It's Hot,' as well as his good friend Gwen Stefani with her first hit without No Doubt, 'Hollaback Girl.' Additionally, Mariah Carey recruited him for 'Say Somethin' with Snoop, and Ludacris had him hop on board for 'Money Maker.'

More recently, Pharrell has collaborated with Madonna on 'Give It 2 Me,' Adam Lambert on 'Trespassing,' Conor Maynard on 'Lift Off,' and Frank Ocean on the track 'Sweet Life,' from the crooner's Grammy-winning album 'Channel Orange.'
