After putting the “Now Playing” stuff in the sidebar, I’ve now added the clever stuff that links to Amazon. The code uses Amazon Web Services to pull back the album art (where it can find it from my iTunes artist and album tags) and a hyperlink to Amazon’s site. The URLS for the link and the art are cached in a local table at this end, so that I don’t overstep the limit of the number of requests that I’m allowed. Whatever that is.
