Jay Z recently relaunched Tidal, a $20-a-month music streaming service that some say could spell trouble for other sites like Spotify.
The launch is the latest in a string of business successes for the 45-year-old rapper, who owns a record label, talent agency, and fashion brand. His estimated net worth is $500 million.
Jay Z has found success by creating his own opportunities.
In doing so, he's gone from being a teen selling drugs on a Brooklyn street corner to a bona fide business mogul.
