Permissions Itunes Folder?
 

Seemingly out of nowhere I have received a message stating that I don't have sufficient permissions for importing music from a CD to my Itunes music folder. Not to be deterred, I logged on as System Administrator, did the import, copied from the folder to a thumb drive and relogged back in as my standard username. How can this be avoided? Get info shows read/write priviledges -so I am really confused
