I’ve been messing around with Amazon API with different types of dynamic searching. So far the coolest thing I have found is Mario Klingemann’s AmazonExplorer at Quasimondo.com. I used the API to conquer my lack-of-time problem with finding artist pictures for every band in my XSPF player. I put the picture viewer back into the player, and loaded just one URL into each track for a cool graphic, that had nothing to do with the band. Now the player automatically queries Amazon and inserts the most likely image for that band in the player. See it Here.
