Isn't the point of getting your music played on the "radio" exposure? How much money did/do artists make per play on normal radio stations? For less-well-known or niche artists, it might be difficult to have your music played on a local or regional radio station, let alone nationally. Pandora, Spotify, etc. provide a variety of artists with national exposure. I'd be interested to see if the artist in question has noticed a correlation between plays on streaming services and her album sales. Or, how about her social network presence. More listeners means more fans, followers, Likes. I've heard of performers using social networking to essentially pre-sell a venue for a live show. There are ways to make money, just have to be creative and innovative - defining traits for most artists.
