Last.FM & Audioscrobbler

Last.FM - Your personal music network - Personalised online radio station - Maybe I'm just late to the game, but Audioscrobbler and Last.fm seem to be onto something here. As we are exposed to more and more content (breadth and depth) - community, recommendations and discovery engines are going to be the key differentiators that media companies will need to leverage to stake a defendable postion in the market (INMHO). Without that, every company playing in the digital media distribution game quickly becomes commodity retailers all hawking the same catalog of goods.
