Fix missing album and song covers in itunes with coverscout

getting a cover for an entire album is easy, simply pick ‘albums with no cover’ from the dropdown selector and click ‘search’

getting a cover for lots of albums follows the same process, however you can select many albums and have coverscout automatically apply the cover for each.

there is an option in the dropdown that will let you select ‘albums with incomplete artwork’ which will show you albums that have artwork missing from any of their tracks, you can then apply the artwork from a track that has a cover to the entire album, or you can have coverscout search online for one.

4) overal experience
overall the app is excellent. it found covers for everything I threw at it.
it does take a play in itunes for itunes to update the cover, which is expected, and isnt anything to do with the app, it has to do with itunes.
i now have a lot of nice covers for my music, which is great when it syncs to my ipad or I play it on my apple tv.

if you have a large music collection and want to make sure you have all the correct covers then I couldnt recommend this app highly enough.
