Beats Music is finally ready to go.

As of Saturday, the new streaming service's website is now live with details about its offerings. And it's officially launching on Jan. 21.

Touting more than 20 million tracks, the obvious Spotify competitor is different in one major way: there is no free option. Instead, users can purchase unlimited subscriptions (sans ads, of course) for $9.99.

Also unlike competitors, as we previously reported, AT&T customers will have the choice of a $14.99 add-on to their current mobile plan, which will allow for streaming on up to 10 devices. Individuals will have access to a 30-day free trial through the carrier, while family plans will receive 90 days free.

As with its flagship headphones line, Beats will also aim to outdo competitors like Spotify, Rhapsody and Rdio in marketing. Using the familiar name and more than $60 million in existing investments, the company has the means to get in front of mainstream consumers in a way its rivals perhaps have not.

According to The New York Times, the service will be promoted regularly on The Ellen DeGeneres Show and in Target. Super Bowl and GRAMMY advertisements are also part of the plan.
