when i download songs and try to drag and move them to the desktop i get this "Cannot Copy Folder:Cannot read from the source file or disk"

Can somone please help me i cant find out how to do this

Why not just make a shortcut from your saved folder (or whichever folder the songs are saved to) to your desktop? In LW tools > options > saving shows you the location of your saved folder. Find that folder on your computer > right click > send to > desktop.

It's safer to have a shortcut on your desktop than a folder. AFAIK, if you happen to get infected then things saved to the desktop are more vulnerable.
