Amazon is providing users with a free $2 Amazon MP3 credit. Enter your favorite song in the box here and allow the app to share on facebook. Then log into your Amazon account to claim your free $2 credit. Promotional credits must be redeemed by 11:59 PM PST on May 24, 2012. They have a ton on songs that start at $0.99 so you could get up to 2 songs for free. My favorite song right now is Somebody That I Used to Know by Gotye. What’s yours?
