Rearranging tracks in a playlist on mobile is a new idea?
Is there some reason this idea is still marked as new?
As Peter mentioned, an idea needs 100 kudos before it gets discussed/reviewed by the Spotify staff.
I am going to mark this idea as "Case closed" as it is not an idea, but a request. Next time, I would suggest to add a post to the original idea instead of creating a new one.
