This is a widget, you can put in the sidebar that display recent played tracks of an last.fm account.
You can set any last.fm username, limit the songs and refresh interval.

LastFM Now Playing

A widget that display recent tracks of an last.fm account.

Simon Wheatley

This plugin adds a widget to display your upcoming events (gigs) from <a href="http://last.fm/" rel="nofollow ugc">Last.FM</a>, with 
options for displaying full venue details, linking, etc. Events are displayed using valid 
<a href="http://microformats.org/wiki/hcalendar" rel="nofollow ugc">hCal</a> <a href="http://microformats.org/" rel="nofollow ugc">Microformat</a> code (makes no 
difference to the display, but plays nicer with the web in general).
This plugin is still in development, but is stable enough that I use it on my own blog. Once other 
people have used it successfully for a while I’ll feel happier labelling it stable.
Please feel free to try the plugin on previous versions of WordPress, I think it may work on 2.2, maybe lower.
Please let me know how you get on.
<h3>Requests</h3>
I’m simply noting requests here, I’ve not necessarily looked into how possible any of these are or how much effort they might require.
<ul>
<li>BUG REPORT: A lot of the timestamps for events aren’t correct therefore, you see “495 months ago.” because it shows a timestamp of 1969 for some reason even though the dates are correct on last.fm. Is there a way you could have it to just display the date instead of trying to calcuate the time until? (Reported by <a href="http://www.deadlydesigns.com/" rel="nofollow ugc">Mike</a>)</li>
<li>REQUEST: Would it be possible to have the link to last.fm events open in a new window so it will not load over top of the blog? (Requested by <a href="http://www.deadlydesigns.com/" rel="nofollow ugc">Mike</a>)</li>
