Sockso is a personal music server for everyone. It's designed to be as simple as possible so that anyone with a mouse and some MP3s can get their friends listening to their music across the Internet in minutes.
A flash player has been added to the Web site so that users can listen to music without a stand-alone application. Playlists are now available in XSPF format, and the whole Web interface has been tweaked. There are bugfixes and other minor improvements.
