Take just about every feature from every streaming music service available, and you you get Spotify. But until today, those of us in the United States were left on the sidelines. No more. Spotify's now live. Create playlists, share music, search from millions of songs, play offline. And, most important, play on your Android phone.

Free invites are going out fast and furious this morning, and there are deals that can get you bumped up to the premium levels pretty quickly. Or if you don't mind paying monthly, $4.99 a month gets you the basic service, sans advertising. For $9.99 a month "premium" (and this is the one most of you will be shooting for), you gain full Spotify access on your Android smartphone, offline mode, and better streaming quality.

We're right in the middle of deep-diving this thing, but so far, Spotify's living up to its expectations.
