Yeah, that was my initial thought. A single play on radio in a big market could easily reach well over 32,000 people. The revenue model for streaming seems to be based on the payout systems that are used for radio. Unfortunately for artists, streaming services like Pandora and Spotify tend to compete against their iTunes and album sales, at least much more so than radio ever did. (in fact radio airtime was mostly considered to be promotional back in the day, very few artists made money from it, and there were a number of scandals were labels payed radio stations to play their music).
