Years on Def Jam: 2006-2012
Signature Def Jam Song: "So Sick" (2006)
Ne-Yo's career on Def Jam hasn't just been a huge success because of his chart-topping hits and albums, he's been the go-to hook guy for the label. Jadakiss' single needs a R&B touch? Throw Ne-Yo on there! Jeezy needs something soulful for the ladies? Throw Ne-Yo on there! Have no idea how to market Ghostface's single? Throw Ne-Yo on there!
