Hip-hop star Jay-Z famously rapped that he has "99 Problems," and he has apparently added Dallas hedge fund firm Highland Capital Management to that long list. The rapper is accusing Highland of delaying a loan so that it could continue to collect interest payments and is suing the firm for $3.7 million in damages. Nina Devlin, spokeswoman for Highland, called the rap star's claims "meritless" and said that Highland "will vigorously defend itself."
