Pandora is now officially available for Windows Phone.

Announced during Microsoft’s launch for Windows Phone 8, the launch is not only a slam dunk for Microsoft, who is working to build its repertoire of high-profile apps, but also for Pandora, which has a business that has started to become very mobile.

Already available for iPhone and Android, more than 75 percent of Pandora listeners have accessed the service from a smartphone or tablet, totaling more than 140 million of the service’s registered users.

We’ve had the opportunity to spend a little time with Pandora for Windows Phone over the past few days.

Live Performance

Windows Phone’s Live Tiles are one of the features that set the operating system apart from its competition, and one of the features that stand out in the Windows Phone version of Pandora.

With Pandora, individual stations can be pinned to your phone’s Start screen for easy access. The particular song that’s playing is also displayed within that live Tile square, making it easy to determine what a particular track is that’s playing without having to open the app, or even navigate away from your Start screen.

While a small feature, it’s amazing how often that functionality actually comes in handy.

Uniquely Windows Phone

The Windows Phone experience extends outside of Live Tiles into the app itself. When you launch Pandora for Windows Phone the app displays the 6 most recent stations you’ve played in tile form, the most recent of those selections larger than the rest.

To start playing a station, you just tap on the album cover for your selection.

Ready for a little change? A “See All Stations” button on the launch page allows you to access a full list of stations you’ve created, and a “Shuffle” button allows you to shuffle all your favorite tunes into a single mix.

The Play screen is also unique to Windows Phone, and displays the album cover in a small square along with Pandora’s traditional thumbs up and down buttons.

A navigation button at the bottom of the screen lets you pin the station to your Start screen, bookmark it, share what you’re listening to with your friends on Facebook, or purchase a track on Xbox Music. You can also let Pandora know you’re tired of listening to a particular tune so it doesn’t pop back up again in your stream for a while.

Kid Safe

Another unique Pandora feature for Windows Phone users is Kid’s Corner. When accessed from the Kid’s Corner portion of your phone, Pandora will automatically activate the explicit content filter on tunes, ensuring that they’re kid-friendly.

If you’re not familiar, Kid’s Corner is a special restricted area of your phone where you can put apps your children enjoy using. While at the grocery store or in the car you can hand your child your phone so they can play their favorite game, or listen to some tunes, giving them access to their own special Start screen while keeping the rest of your phone’s functions restricted.

Free To Play

Windows Phone users can access Pandora ad-free until the end of the year. That’s a huge advantage over iPhone and Android Pandora listeners who can only access an ad-supported version of the service for free, with listening capped at 40 hours per month. After 40 hours, those users have to pay $.99 to keep listening to ad-supported radio for the remainder of the month.

Microsoft is picking up the bill until the end of 2013 not only for Windows Phone users to listen as much as they want, but also for them to do so without ads.

You can download Pandora for Windows Phone now from the Windows Phone Store.
