Just added a recently played tracks to my sidebar. My intentions was to add the Last.fm weekly tracks box but it was to big for my sidebar. This lead me to search their forums for a easy way similar to my custom xfire sig with my last track played. I found the answer through the Audioscrobbler sight on a WIKI called Recent Tracks On Your Blog. The instructions are simple enough, first you register your RSS feed (Last.fm provides this for free) on FeedDigest.com. You select a template and then Feed Digest gives you the code to add to your sight. So watch the sidebar for some of my musical recommendations.
