iPod House Cleaning

It's time to clean up my iTune, the songs in my iPod Classic and the songs in iPod Touch. So I used iLyrics to update some lyrics, and then attached and updated some album covers for that does not have a cover. Finally I am adding new audio book to learn during commute. Everything seems to work out fine as expected. I know, when dealing with computer, there's always a chance that something doesn't work out. This time it's not the case.
