The developers behind Peter Gabriel-supported music recommendation software The Filter have announced a social version of the application, designed for inclusion in Facebook and MySpace pages.

Software developers Exabre call the new version the "digital equivalent of rummaging through your friends’ music collection".

This version of The Filter lets music fans publish a widget or playlist on their blog, MySpace or Facebook page. This widget will share a user's Filter playlists and offer site visitors a snapshot of their music collection, which us updated dynamically as new music is added to the collection.

Exabre's also updated the mobile version of the software, which lets users create playlists from music stored on a mobile phone simply by selecting one song.

Rhett Ryder, CEO and co-founder of Exabre said: “We may not have been first to launch an application for Facebook, but we believe that in time ours will prove to be the most compelling

The Filter was originally launched in 2006. Now available for Mac and WIndows systems, the software creates playlists from an iTunes or Windows Media Player music library, playlists designed to match a user's mood or activity.

These playlists can then be updated automatically to an iPod or MP3 player. The Filter also recommends new music to the user and takes them to the store where they can purchase it.

A user’s MyFilter page shows relevant content and YouTube videos related to the song they are listening to.

The Filter is available as a free download for Windows (iTunes and Windows Media Player), Mac (iTunes) and Nokia (Series 60) mobiles.
