Last.fm is exactly the sort of service that I think works well on Facebook. If the ostensible point of social networking is to connect with your friends, then sharing your music listening habits – a key marker of identity in North America – seems a pretty good way to do so. Their new Facebook app is , however, subpar – all it does is list the tracks you are listening to at that moment and not terribly reliably. The previous app linked neatly to one’s last.fm profile and had little pictures of a few of the top artists in your list. It seems like a small thing, but those visual triggers are exactly the sorts of cues that would cause someone to click further. It’s also simply more aesthetically pleasing – the new one is rather plain.
I still love last.fm though – it works for me as a music nerd and as someone who’s borderline OCD 
(Must scrobble, must scrobble and then wash hands seven times…) Hopefully they’ll get their shit together and merge the best of the new and old apps.
