Last.fm (http://www.last.fm) is a free website/service that records the titles and artist of every song you listen to (via a free download of the Last.fm client), and displays them on your own Last.fm page. The program is currently available for Windows, OS X, Linux and more, and supports iTunes, Windows Media Player, Winamp, and much more. Sign up here.
TMBW users with Last.fm accounts can put the Last.fm Chart templates on their user page to let others see what they're listening to. There are two types of Last.fm charts implementable on your user page:
Now you can use the new Last.fm Quilt flash graphic on your user page. To add it, type:
{{LastfmQuilt|username=Last.fm username|type=albums or artists|color=black, grey, red, or blue|rows=3, 4, or 5}}
Here's what the quilt looks like! (this one is set to albums, blue and 3 rows)
To add it to your page, type:
{{Lastfm|username=Last.fm username|type=See below, and then put the type of chart you want here|color=black, grey, red, or blue}}
