Money for Music

Reading this semi-widely shared piece by Damon Krukowski- I really think the analogy is wrong. Pandora is like having your song played on the radio, not like selling 7" of vinyl. When I buy a piece of vinyl, I can listen to it as many times as I want, or at least until the grooves run down. He tries to compare the royalty for 7,000 plays of a track on Pandora to 7,000 sales of a single?? It's more like a radio station with 7,000 listeners playing it once. How much is Galaxie 500 making in radio royalties? I haven't heard them on the radio for 15 years. They should be comparing their $1.21 to $0.00.
