Use Your iPod shuffle without Using iTunes

You'll have to have a fairly recent installation of Python running on OS X for it to work, but if you have wished that you could simply drag your MP3s over to your iPod shuffle without having to launch iTunes, then
iPod shuffle Database Builder is for you.
An added benefit of using this tool is that it enables you to use the iPod shuffle on as many computers as you like without having to pair it again and again to a new iTunes Music Library. Even better, the program is only 8k and will work on any OS with Python installed, so there's no reason not to put a copy on the iPod shuffle itself.
