Share a song – get credit. Amazon is currently giving away a $2 MP3 credit to its music store. All you have to do is click on this link, enter the name of your favorite song title (or any song title, really), and click on Share & Claim. Then, you will need to give Amazon’s Facebook app permission to connect with your profile. Upon completion of the “Share & Claim” action, a $2 MP3 credit will be automatically applied to your Amazon account. Then you can use your credit to score a couple songs for free. The song you select will be displayed on your Facebook Timeline, though you can easily go back and delete off your page.
Amazon MP3 music is available only to customers located and with billing addresses in the United States.
Limit one promotional credit per customer.
