This is just a simple script that will recursively download album art for your mp3 collection stored in an Artist/Album folder structure, or at the very least …/Album folder structure. This script uses Amazon and it's product advertising api to get the art. The script will recurse through your folder(s) and add a folder.jpg file at every leaf directory that it finds mp3s in. Most players are smart enough to use this file for the album art.

The only requirement to run this script is that you download and install the Python Amazon product api. That, in turn, requires the Python lxml library. If you use the easy_install method (or have that installed) when you install the amazon product api, it will automatically pull in the lxml library for you.

The script itself is actually quite simple since all the heavy lifting is done by the Amazon product api library. Make sure you change the API_KEY, and SECRET_KEY to whatever your key values are that you obtained from Amazon. If you do not have a key pair, you can get them for free here. You will also want to set your own BASEDIRS to the directories where you have your music. Once you have that all done, just run the script: python getcovers.py.

You can also download this script here. This is a bit of a quick and dirty 10 minute script. I will probably add some command-line opts later when I have time, but for now it functions well.
