Moving songs and folders
Select the songs or folders you want to move, then navigate back out
of this view and continue to navigate into the destination folder. Tap
the "Move Here" button top right in the "Navigation Bar" and the selected
items will be moved.
You can only move physical files or folders stored on the device and
the destination folder must be one that may contain physical files.
The "Move Here" button will be grayed out or disappear if moving is
not possible.
