Following a rather mysterious tweet — teasing something big enough to warrant a sleepless night – Corporate VP of Windows Phone Program Management and Design Joe Belfiore finally spilled it: Pandora has arrived on Windows Phone.

On top of this, consumers in the US will be able to enjoy a completely ad-free experience in the app throughout the rest of 2013. While the rest of the world will miss out on this perk, Belfiore did state in a followup tweet that “we’ll try to find something else fun in a few days” for non-US users. To grab Pandora, just head on over to the Windows Phone Store (if the link isn’t working just yet, give it a bit of time, it’s still fresh.)

For those of you who may be unfamiliar with Pandora, it is an Internet music streaming service which specializes on making song recommendations to users based on a number of factors, including musical attributes — taking advantage of the Music Genome Project — user feedback, listening history, and more.
