They could lose them in the other direction as well. Unlike you, I don't mind podcasts being thrown at me. However, having come to enjoy a couple of the podcasts on offer, I'm not offered a way to subscribe to the pay versions of those podcasts, so I end up subscribing directly. Unfortunately, the Spotify app doesn't provide me a way to add my private RSS feeds from those subscriptions, so I spend much less time on Spotify and question whether I need the service at all.
