What's wrong with specialist services? I love audiobooks, use audible a lot, yet that keeps trying to push it's podcasts on me. I also like podcasts but I have a different app for that, with different features and demands as required by podcasts. I don't often listen to music so have never bothered with Spotify, but music player apps are rarely good for playing audio books or podcasts so why are they all trying to combine them just because they're audio? It's like making a fridge-freezer-oven-microwave-blender device just because they're all kitchen things, so there must be synergy.
