I've written before about PandoraFM which allows you to "scrobble" your Pandora tracks to your last.fm profile. Now there is a new Facebook app, What I'm Listening To, which displays your current last.fm playlist on your Facebook profile. So now your Pandora music "audit trail" is displayed on Facebook via last.fm.
I'm not so much interested by the fact that my questionable musical tastes can now be shared on Facebook so much as this is another example of the useful inter-meshing of data and applications that seems to be so much easier to achieve these days.
Interesting musical times indeed.
