Last.fm is a service that tracks what you listening to, usually you install a little piece of software that "talks" to Windows Media Player, iTunes or Winamp, or whatever audio playing software you use, and then it reports back to the website, Last.fm and then it generates statistics and stuff about who you listen to, etc...You can view my Last.fm profile here, it'll make more sense after seeing it :)

So the new thing our site does is allows you to plug in the latest song in your Last.fm profile, I mean you could type it in or something, but this is a neat little interface between us and another website.

It's not like ground-breaking, just kind of cool :)
