Background - I've got a first-gen iPod touch. It has an 8gb capacity. I have around 40 gigs of music. Because my library is larger than my iPod, I obviously cannot just have it synch with my library. I am fine manually adding songs to my iPod, but what bugs me is that I have no clue how to "update" those songs without removing them and re-adding them (if lyrics are added, artwork, play count, etc.). Is there a way to have my iPod touch synch the only files I choose to put on it? Thanks.
