I am looking for ways to clean up my Harddrive. I know that I've been ripping and downloading a lot of music recently but I noticed something outrageous, I have 8 more GB in my iTunes library then should be there. Why? I checked it thoroughly for Podcasts and all songs that aren't actually in the library and when added up the actual amount it still should be is 13.20GB MAXIMUM. Can someone help me with this problem or explain why I'm being an idiot?
