We knew it was coming, but Europe's beloved music service just officially launched stateside, bringing with it 15 million tracks with on-demand access, MP3 import, an offline mode, and social media integration. The streaming music service is currently in an invite-only beta phase, but you can sign up for an invitation or jump the queue right into the service's Premium or Unlimited subscription tiers. Groove on over to the source link to sign up, and start piping millions of free tunes directly to your desktop -- once Spotify sends the welcome nod to your inbox, of course.C
