If you've purchased anything from the iTunes Store, or other online music stores like AmazonMP3 or eMusic, the songs or albums you buy come with album art. But for songs gotten by other means or music ripped from CDs, album art may be missing.
While there are a number of means to get album art for your iTunes library, probably the easiest is iTunes' built-in album artwork grabber. Here's how to employ this easy-to-use tool to get album art in iTunes.
The last couple of steps in this article provide other ways to get album art for situations where iTunes can't find the right artwork.
Use iTunes to Get CD Cover Art
The iTunes album art tool scans your music library and Apple's servers. When it finds art for songs that you have, even songs that you didn't buy at iTunes, it adds them to your music.
The way you do this depends on what version of iTunes you're running. In iTunes 11 and higher, click on File -> Library -> Get Album Artwork. In older versions of iTunes, go to the Advanced menu. Then click on Get Album Artwork.
In some versions of iTunes, a window pops up letting you know that, to get album artwork, you have to send information about your library to Apple but that Apple doesn't store that information. If you still want to go ahead, click Get Album Artwork.
The status window at the top of iTunes will start showing a progress bar as it scans your library for albums and downloads the correct art from iTunes. How long this takes depends on how much music needs to be scanned, but expect to spend a few minutes. The art is automatically downloaded, categorized, and added to the correct songs. You don't have to do anything other than wait for the process to complete.
