With Slacker’s latest launch of their public radio programming from American Public Media, BlackBerry Empire is giving away 3 3-Month FREE Premium subscriptions!. All Slacker listeners can now enjoy customizable versions of Marketplace and The Current. The Current is particularly good for music discovery, and I recommend checking these stations out. To enter Slacker Premium Subscription contest all you have to do is drop a comment explaining why you would want a free premium subscription for Slacker Radio!
