This script keeps users' recently played tracks table up-to-date without the page refreshing.
If the script doesn't work for you then please email me as 'andrew as indiegigs dot co dot uk'. To help me identify bugs, please follow the guidelines below.
When emailing me about bugs, please do the following. See if the script works on my userpage. If it doesn't then email me with your Firefox/Greasemonkey version numbers, what you see if anything. It would also help if you attached the HTML of my user page. Simple go File->Save As in Firefox and attach that to your email. If my user page does work then email me with the URL, your Firefox/Greasemonkey version numbers, what you see if anything and the HTML of the page as an attachment.
Installing the Firebug extension and letting me know the error message will also greatly help.
