Cover art can make a difference
In 1994 I was walking through the Washington, DC Tower Records in Foggy Bottom and saw an album cover that blew me away as a large poster on a wall. At first I just saw the continent of Africa, including Madigascar. But as I grew closer I could see a slightly contorted man in a suit. I walked backward and forward blurring my vision to get the original image I saw then stood in wonderment for a moment before tracking down the CD to buy. This may have been the first and only album or CD I bought based solely on the cover art. I was afraid I would not be able to find that disk again if I did not buy it. I really wanted the poster too, but at the time I knew it would not fit well in my studio apartment as the initial viewing and reviewing the image helps with distance.
Today I am finally ripping Manu Dibango's Wakafrika from the disc I bought years ago into my TiBook with AAC at a 160 bit rate to ensure the wonderful quality of the music. The music on the disk is equal to the cover art and I keep forgetting I do not have it to take with me on travel. Now with iTunes 4 I can also have to cover art.
