5. Def Jam Recordings
January 28, 1984, T La Rock and Jazzy Jay released “It’s Yours,” the first-ever single to have a Def Jam emblem on it. Later that year, LL Cool J dispensed “I Need A Beat,” the first single to be released after the label’s founders, Rick Rubin and Russell Simmons, came together. Since then, and over the past 30 years, the label has been the mainstay behind some of the greatest hip-hop projects to be heard around the world.
