I am relatively new to iPhone (i have the 4S) but am managed to get some chosen tracks from MacBook pro to the iPhone. The problem is that some of the album covers did not transfer over and when i look at coverflow in my iPhone it has inserted some very strange graphics in there (such as SunChyme by Dario G has the BBC Wildlife Fund logo in it!) I have no idea where it is getting these from. 
How do i correct it and make the album covers sync over to the iPhone?
