Album artwork not found for album in iTunes music store

Question

I have ripped the Foo Fighters album Echoes, Silence, Patience & Grace CD and was hoping to grab the album artwork in iTunes, but iTunes claims "Artwork for 'Foo Fighters - Echoes, Silence, Patience & Grace' could not be found".
I have double checked the spelling of the artist and album names, as well as checked for errant spaces or other characters, but I don't see why iTunes doesn't want to download this album art.
Has anyone overcome an issue like this before?
Thanks.

Yes, statistically you are correct. Although when you take into account that additional art enclosed in each song could in some cases cause a single file to tip over into the next 'block' of disk space (is HFS+ using 4K blocks these days?), and multiply that by the 13,600 songs I have ripped into my iTunes database, it is not something that interests me.
But if you're only missing a few album covers, then adding them manually won't add much space. I let iTunes find what it can find, then add the few it doesn't find manually.
And yes, if you look at my previous posts I have double-checked and even re-entered by hand the artist and album names to exactly match the ITMS entries with no success.
You wouldn't be able to detect, for instance, an extra space at the end of an album name. It's also possible that the artwork database doesn't exactly match the displayed data in the iTunes Store. You might be right that it's a problem with your iTunes, though; mine is almost never unable to download artwork.
