This
Last.FM plugin allows you to show your recently listened to tracks on
Last.FM as a widget on your blog.
It will display these tracks as a list, with hyperlinks to the URLs on
Last.FM so your users can see what music you like to listen to.
You can now also show a list of your friends on
Last.FM with a separate widget!
It's also very easy to show your user shouts as a widget too!
Installing it is also very simple. See the installation menu for instructions.
