Any serious music collector needs to be able to sort their collection. Files they can create label and put albums songs and playlists into ,(along with the ability to order the items in a file as they see fit) is best. I don't know how Pandora misses this obvious need.
Do they have any serious music collector at the decision making level ? They should get some.
I want to be able to sort playlist, prevent duplicates, and rename folders. Can't believe these aren't already features since these are most common on everyone else's app.
