In 2003, Jay-Z shocked the hip-hop world by releasing The Black Album and announcing that it would be his last solo record before retirement. Asked to explain his sudden exit from rap, Jay-Z said that he once derived inspiration from trying to outshine other great MCs, but had simply gotten bored due to a lack of competition. "The game ain't hot," he said. "I love when someone makes a hot album and then you've got to make a hot album. I love that. But it ain't hot."
During his hiatus from rapping, Jay-Z turned his attention to the business side of music, becoming president of Def Jam Recordings. As president of Def Jam, Jay-Z signed such popular acts as Rihanna, Ne-Yo and Young Jeezy and helped effect Kanye West's transition from producer to bestselling recording artist. But his reign at the venerable hip-hop label wasn't all smooth sailing; Jay-Z resigned as Def Jam's president in 2007, complaining about the company's resistance to change from ineffectual business models. "You have record executives who've been sitting in their office for 20 years because of one act," he lamented. Read more about Jay-Z here.
