Last.fm Markup

I run a music blog. I’m often using Last.fm as my resource of choice for band information. I was wondering if it would be possible, or if it already exists, to have a plugin to use the Last.fm formatting/markup like they have on their journal system over there.

i.e,

[artist]Kyuss[/artist] would auto format to a link to the Last.fm Kyuss page.

Thanks in advance.
