I would love a feature where Spotify automatically aggregates all the episodes of the podcasts I follow sorted by latest release. This way I can keep up on all the latest episodes without having to jump between all the different podcast pages. I can just press play!
This same feature would be great for music as well. Spotify could aggregate all the latest song releases by the artists I'm following into a regularly updated playlist sorted by release date. This way I could stay up-to-date on the latest music from musicians I love without having to check out a million different artist pages.
