I guess you had a good reason for removing a favorite feature such as Running. I am sure you already know that many people like me, cancel their subscription and you still think it will be more cost-effective if you remove the feature. So I am not going to push you for bringing it back. However, I don't understand why you don't make all of those playlists available now. If you don't want to maintain the bpm detector feature, still you can publish all of those playlists based on their bpm. For instance the playlist for Hard Rock, bpm 160. Or Heavy Metal bpm 165. At least people like me who know their desired bmp can use your service and stay a paying customer.
