David Bowie's entire catalog of songs has officially been sold to Warner Music Group by his estate for an estimated $250 million. This means the group now has the full rights to almost all of David Bowie's recordings. But Bowie, just the latest music mega deal. Just last month, Bruce Springsteen sold his entire catalog to Sony Music Entertainment at what in fact maybe be the biggest transaction ever for a single artist's body of work. In addition, John Legend also cashed in by selling rights to his songs from 2004 to early last year. Culture Correspondent at NPR, Anastasia Tsioulcas, joined Cheddar to discuss more.
