Spotify has announced that it intends to become a blog aggregator. So, instead of using RSS to identify the podcasts you want to follow, you may have to go through Spotify to listen/watch some podcasts.
This arrangement could offer financial incentives to both content creators and the music streaming service. In the future, some of the more popular podcasts may require that you be a Spotify subscriber to listen. In other cases, Spotify could add ads to other podcasts that it makes available to those who listen for free. Both the ads and the subscriber fees could provide a source of revenue for the content creators. If what is known about the compensation for musicians, the pay for play may not be substantial, but some may receive special incentives and all might receive something.
