That soulds like alot of work, what I do may also seem like alot of work but it works perfectly for me.
Itunes, I create the album playlist, the on the first song, I right click then go to "Get Info" then I click on the "Artwork" Tab, then I click on the Add button. I usually find my artwork on
Amazon.com Music: Save on thousands of CDs from your favorite artists, I save the Artwork of the album i want and Add it from the "Artwork" tab. Right Click on the Artwork from this tab to copy and past on your next couple of files.
Once you do it a couple of times, you can do it pretty fast. Trust, its very easy!!
