I set up a friend's iPhone on my computer and am trying to put all the checked songs in my library onto it. I chose to only sync 2 playlists that I have and when the iPhone syncs, it only puts the songs that are in those 2 playlists on the iPhone. It doesn't put any other checked music onto it. I don't know why it is doing this, but I just want all my checked music and 2 playlists onto this iPhone. Can anyone help me out?
