Bruce Springsteen has sold his music rights to Sony in an estimated $500 million deal, US entertainment publication Billboard and the New York Times reported Wednesday. The sale includes the singers recorded music catalog as well as his body of work as a songwriter -- including classic hits such as "Born in the U.S.A." -- sources familiar with the deal told by both media outlets. No public announcement has been made. Sony Group and Sony Music did not immediately return AFPs request for comment. Springsteen is the latest star to reportedly sell his catalog, following deals made by Bob Dylan, Stevie Nicks, and Neil Young for part or all of their works. Song rights are seeing a purchasing boom as financial markets are increasingly drawn to the lucrative portfolios as an asset class. Last year, Dylan sold his full publishing catalog for a reported sum of $300 million to Universal Music Publishing Group, while Fleetwood Macs Nicks sold a majority stake in her catalog reportedly for $100 million. Springsteen, 72, has been with Sonys Columbia Records for the entirety of his 50-year career, selling more than 150 million records.
