OS X :: Write Permissions In ITunes - Can't Import New Files

In short, I can't import any new files into itunes except for from the itunes store. When I downloaded an mp3 online, and tried to drag and drop it to itunes in order to import, it says "Attempting to copy to the disc Macintosh HD failed: You do not have enough access priveleges for this operation. I am the only admin on the computer, i have gone through music>itunes>Itunes music and made read/write for me on all three under "get info" when trying to import a CD it says "the song couldn't be converted, you don't have write access to your itunes media folder or a folder within it" I spotlighted "itunes media" and found nothing. Next I repaired disk permissions from disk utility, still the same problems.
