Album covers from the iTunes Store
iTunes Match can only download cover art for albums in your music library that are also available in the iTunes Store. For any albums that aren't in the iTunes store, CoverScout comes to the rescue.
Your cover in the cloud
Thanks to iTunes Match, covers that you add with CoverScout are then automatically added to your iPhone or iPad with iTunes Match. So add a cover on your Mac and "boom", it'll show up on your iPhone.
Find the right cover
Unlike iTunes, CoverScout allows you to search for specific covers and even edit what you find. A must for music lovers. The fact is, you can fetch some covers with iTunes, but to get the right covers for ALL your albums, you'll still want to use CoverScout.
