I lately had a my PC is now renewed to manufacturer configurations. I down loadable the newest edition of apple itunes last night. I added all my songs from my hard drive to the collection. When I try to synchronize mp3 player and iphone traditional only part of the songs syncs and the art work is not there. There are 1184 collections in the apple itunes collection, only the characters a-c create it to mp3 player and iphone after over an hour of syncing. It looks as though all the songs is going on by viewing the apple itunes system synchronize but its just not on mp3 player and iphone.
