But the difference is that users have control over the music on Spotify. Even with the free version you can listen to a song when you want, as many times as you want. So as long as they're a Spotify member, a user essentially owns the content on there. With radio it's more of a teaser. You might hear a song you like but you'll have to purchase it if you want to listen to it on repeat.
