(Pocket-lint) - Spotify has officially launched a paid podcast subscription product in the US. It is allowing, initially, select podcasters on its platform to charge for content by offering subscriptions to their shows. Here's everything you need to know about how Spotify podcast subscriptions work. How to tell if a podcast isn't free on Spotify Subscribers can listen to paid podcasts inside of Spotify or a third-party app through a private RSS feed. In Spotify, paid content will have a lock icon where the play button typically appears. To unlock a show, you will have to go to a dedicated Anchor page, which podcasters can put in their show notes, bio, and episode descriptions. It's worth noting you can't subscribe directly within the Spotify app, which means Spotify won’t have to pay Apple for any subscriptions sold under its App Store terms.
