It's hard for artist to make money by selling their music. They make way more by touring. I bet he'll continue to tour and he probably keeps the right to continue to sing his songs without having to pay a fee. It make sense to sell them. The company that buys them has an incentive to make sure they will continue to be streamed which only increases the demand for his concerts.

He sold the rights to his songs so that's it; he gets no more money from them. 200 million is a good chunk of cash. He's set for the rest of his life even when you factor in taxes. Good for him.
