It’s nice when companies keep their word. Spotify kept its promise and officially became available in the U.S. today.

Actually, the free version is not available unless you receive an invitation; good luck with that — they seem to be in limited supply.

The premium version of Spotify, which costs $9.99 per month, provides full access to the service, including the ability to access it via a mobile phone For those who only intend to play music from a Mac or Windows desktop, the Unlimited plan at $4.99 provides access to the Spotify catalog without advertisements, along with unlimited streaming.

If you are the type who likes to share your playlists with others, know that you can share your Spotify playlists on Facebook, and the service will identify which of your friends are using it. You share a link to the playlist in a wall post or tweet, but in order for your friends to open the playlist they will need the Spotify app on their computer.

Readers, have you tried Spotify in the U.S. yet and if so what did you think of it?
