PlaylistNation is an interesting application. It facilitates the free, legal, and private way to view which songs our friends and family are listening to on their computers. The PlaylistNation client works along with all popular audio player programs and can post the track names of the song files played on the private online account of any user. From the online 'My Music' page, the user can review which songs his/her friends have listened recently and can leave comments about any song. User can even post a list of most recent tracks onto own personal homepage or blog. It's a great way to learn and experience music.
