There is this now playing plugin for winamp which lets you send current IDtag data via GET/POST. Nice.
It’s beta and there are still some issues but it works. I have build a little flashticker showing what’s now playing on my winmap. The time of the last update is shown too. It updates on page reload, there is room for improvement. The update checking and display could be moved to flash, so it doesn’t depend on reloading.
 
The possibilities of what you could do are endless. You could save and build an interface to your whole playlist of recent x days/weeks/months. Or display the cover with a link to amazon. Or..
 
What I like most about it, is the connection between the real life of the blog owner and the blog as hers/his web representation.
