I have long playlists each with mutiple genres. As most tracks have the genre in its information i thought it would be a good idea to have that on the list when selecting a track. I believe spotify also has the genre in each tracks URI too which would be very beneficial to doing such a thing.
Hi Ross,
Thank you for your post.
I added your request to our user request list.
Thank you for sharing, we hope to provide this feature in the future.
I second this… ( have already posted about the same topic last week actually!)
To be able to sort playlists by Genre is a Necessity.
Be awesome if this could be implemented
