Like U2, Madonna toured for the first time under a long-term multirights Live Nation deal (hers valued at $120 million), and also like U2 it’s a performance-based pact. Madonna delivered: Her Sticky & Sweet tour tacked on a “victory lap” run of international stadium dates that solidified the trek as the highest-grossing tour ever by a solo artist. Madonna’s CD sales were well off the pace of her peak hitmaking years, but still more than respectable at physical and digital. Because her songs come from a wide range of writers, the publishing pie is pretty well-sliced. But her branding, licensing and merch efforts are among the most diversified and lucrative in the music business.
