You can pick up a FREE $1 Amazon MP3 credit just by logging into your My Coke Rewards account. You can use this for a new song or even album to download to your playlist. I love this to add new music to keep my workout playlist to keep me from getting bored.
Hurry, this deal is valid through 11/4/2013.
