Automatically download album artwork from the iTunes Store. (since v. 7)

I've got a love/hate relationship with the iTunes Store - specifically, I love to hate it. I resisted signing up for an account (which requires your credit card number before you buy anything!) until iTunes version 7, which can automatically download album artwork for your tracks from the iTunes Store. Now, album artwork wasn't a big deal to me, until v. 7's Cover Flow view, which looks like a jukebox flipping album covers while it's playing.

To grab your album art, you must be signed into the iTunes Store (and it turns out you can register using a PayPal account). From the Advanced menu, choose "Get Album Artwork."

P.S. There are a few non-iTunes Store ways to download album art for your library. LH reader Craig recommends Corripo for Mac and Mambo for Windows, both free.
