iTunes and Microsoft MP don't use the same methods to get such things. I can update cover art in a few ways in iTunes. Do we need a tutorial on the ways?
If so, try this one -> http://www.techradar.com/news/computing/apple/how-to-find-missing-itunes-album-artwork-940979
Both automatic and manual methods are covered there.
Why is it that some of the albums I have on CD don't have cover art in iTunes? When I rip the same songs using Microsoft Media player the cover art comes up? How is cover art updated in iTunes?
