About six months ago, we wrote about ExtensionFM, an extension for Google Chrome that helps index the MP3s you run across while surfing the web. Yesterday, the company introduced a brand new version of the plugin and announced that it has changed its name to exfm.
In addition to the name change, exfm version 2.0 has a ton of new features, including integration with Twitter, Facebook and Tumblr. The result is that the organizational tool has turned into a bonafide social music discovery engine.
The way that exfm works hasn’t changed; it still scrapes websites you visit for embedded or linked MP3 files and adds those files to your library. It also provides the option of playing them or adding them to your musical queue via the browser extension.
The difference is that exfm now has a very robust social component. That means that in addition to being able to link to your Last.fm account to scrobble tracks you listen to or discover, you can also pump in music files shared via Twitter, Facebook or Tumblr.

So when I connect my Tumblr account to exfm, it searches through all my Tumblr friends and adds all of the songs they share to my library. It also shows me a real-time feed of tracks they are sharing throughout the day.

The same goes for Twitter or Facebook. MP3s shared via Facebook and Twitter also become part of your overall library.
You can also share songs you run across with your friends using Facebook, Twitter, Tumblr or e-mail.
Additionally, exfm has now added the ability to “note” songs — basically think of this as a way to favorite or “love” a track. This is a great way to highlight music you discover and want to return to later on.
Exfm has introduced its own social network of sorts. Users now have their own profile pages. Your profile page lists all your “noted” songs and also shows who you follow and who follows you. Your exfm friends are added to the recent activity feed on the main exfm homepage. Again, this serves as a great way to find and discover new tunes.

Honestly, we can’t stress enough how much the ability to suck in shared music from your social networks adds to the service. It really propels exfm from a utility that was convenient — but ultimately not very sticky — to something with very real value.
Our only request would be the ability to create custom playlists that could be shared with friends.
Exfm is available for free.
