Mark Zuckerberg's favorite music streaming site, Spotify, will open its doors to American users as early as next week. But in the United Kingdom, the Swedish startup just secured a potentially game-changing contract with Virgin Media to offer their services directly through broadband, cable television, and telephone lines. This means that Spotify customers, both free and paid, will be able to access the cloud music service from set-top boxes and home phones, but more importantly, the deal will allow Virgin to bundle Spotify with their broadband packages. Virgin executives hope the ease of access will clamp down on music piracy.
