Hi @Cwallbruch, thanks for posting!
Our Featured Playlists are updated on a weekly or monthly basis to keep things fresh. Your personalized playlists should update every week, but some playlists that were created for more niche topics (such as "One Hit Wonders") may be updated less frequently.
Once one of the Featured Playlists that you've collected has been updated, it will appear at the top of your Playlists collection.
Hope this helps!
