OK, so I downloaded about 100 or so new songs yesterday from iTunes and they all had the cover art on them whilst on iTunes...every single one of them. I then synced my iPhone to it and transferred all of the songs. When I turn on my iPhone all the songs have downloaded but out of those 100 songs about 6 of them have no cover art, even though it was on iTunes? Any help on how to get the rest of the cover art on these songs would be greatly appreciated.
