Rap mogul JAY-Z will reportedly be ditched by his Def Jam record company - because bosses are sick of his excessive demands. The star - real name Shawn Carter - was reportedly keen to leave his post as president of Def Jam, a subsidiary of Universal, in favour of a new contract at Columbia, but new rumours suggest his current label may drop him first. Rumours of a label change have been rife in the music industry after Jay-Z was reported to be unhappy with Def Jam following the appointment of producer/performer Jermaine Dupri as the president of their urban music division in February this year (07). But now the rapper could have the decision made for him as his contract with Universal is due to expire at the end of this month (Dec07) and negotiations for a renewal have so far proved unsuccessful. A source tells New York Daily News, "People have lost count of how many times he's come out of retirement. "Everybody knows he's not around the office much. Everybody at Universal loves him, but they can't justify paying him the money he wants when so many people have been laid off."
