I mean, you only have to open the main Spotify page. I also get podcast content pushed to me (half the main page/search results are always podcasts) and I've never even listened to one.
Again, my main spotify page ask me to continue listening to the podcast I already listen to, plus random daily playlist for music(which I actually really like a lot of the time). I don't get new content showed to be all too often, maybe a new artist a week?
