Pandora for BlackBerry was picked as the top streaming media app for BlackBerry in our Best of 2009 Awards, so we figured it would be worth giving it a quick A to Z for those of you who haven't tried it out. Pandora is totally free, and lets you stream custom radio stations to your device. You can create stations right from the app, and tweak them to your liking with Pandora's "thumbs-up" and "thumbs-down" buttons. The app syncs up with any stations you've created through the web or another device, and gives you a quick and easy way to stream music on the go. This is really a "no frills" app - its does what it needs to with no excessive options or erroneous features. Check out the video above for a look at what Pandora has to offer.
