This is interesting. The Skype install code points toward a music application called Vibes. This piece of code all but confirms it. Facebook will be launching a new application called Vibes. As in good vibes. It connects with a music download dialog in the page, apparently.
This news coincides with Spotify’s announcement that it is launching in the US. And a Spotify-Facebook partnership has been rumored. The “Vibes” name makes sense too: The Skype deal was called “Peeps”. I think we can safely expect a launch by the end of summer. This will be interesting to watch.
