Unable to rearrange songs in a playlist:(

[wilkobecks]

I cannot for the life of me figure out how to drag and rearrange songs in my playlists, and it is driving me crazy! When I try to drag and drop on my desktop I get the circle with a line through it icon meaning "no", and on my phone I don't even get that. (Android). I have read that I should unsort the songs, but they are currently only sorted as "custom", and I cannot choose the completely unsort them, I can only choose to sort them a different way. 

I just want to drag and drop songs, nothing crazy!
