I recently updated all the albums on my itunes with pictures. So I deleted all the songs off my ipod touch and decided to put them back in. After i deleted them, it wouldn't let me drag and drop any music files. The only way I can get files in there is if I Autosync them in. After that, they appear on my itunes in a gray font, and they won't let me click on them or do anything with them. What's up with that?
