I recently backed up my music because I was changing operating systems. However, only when I opened itunes in the new install and put in my old libraries did I realize that I had missed backing up some folders with music on them. Hence, the result being a ! next to the songs, the song being only on my iPod touch not my PC itunes library. I've tried a variety of copy apps to copy songs from the ipod, but I couldn't find any that could specifically locate the !, missing songs, and copy them back from my ipod onto my PC. Any advice would be much appreciated!
