Amazon Associates Web Service (A2S) script

I am looking for a script that is very simple to code for a person with an Amazon A2S skills. I see some difficulties for you, if you've never coded for Amazon A2S. Basically what I need the script to do, is to retrieve data from the following top lists: a) Bestsellers in Music b) Today's Top MP3 Albums c) Today's Top MP3 Songs d) Today's Top MP3 Artists Lists b), c), d) are accessible at the Amazon's MP3 downloads page, http://www.amazon.com/b/ref=sv_m_7/002-2894958-3771267?ie=UTF8&node=163856011 List a) can be found at the Amazon Music home page, in the rightmost column. The right way would be to code a PHP script that would request this data using Amazon Web Services interface, parse resulting XML file and provide a palin text list of relevant data (ASIN's, titles, artists, release dates, tracklists for CDs and so on). The wrong way would be to make a script that downloads the top lists, parses HTML and extracts the data.
