Spotify has launched in the US today! It's been a long wait to try and use this awesome service that has been available in other countries for a while. They are doing a controlled launch so be sure to head over and request an invite. If you use Klout you may be eligible to get in with the Spotify Klout Perk today without waiting. The crew at TNW wrote a great Beginners Guide to Spotify to get you started. Time to use Spotify!
