Helps you find new Spotify music
If you didn't already get in on the US launch of Spotify, the dominant freemium music streaming service in Europe, head over here and get an account. Once you're done with that, come back, because you're gonna need these tools to get the most out of Spotify. Spotify's pretty decent out of the box. It has 15 million songs—which I think is the most of any streaming service right now—and a wide userbase, so you have a higher chance of finding friends who are on it. But it's also missing a lot of things.
