You can use your Mobile phone in game to purchase and download new MP3 tracks to listen to while you play the game via Amazon. If you hear a song you like on the radio, you will be able to 'mark' the song by dialling ZIT-555-0100 on Niko's phone.

They will then receive a text message providing the name of the song and the artist. If the user is registered on Rockstar's 'Social Club' website, they will also receive a real world email with a link to an Amazon.com playlist where all of the player's marked songs will be listed and available to purchase.

Initially, this service will only be available in the US, but it sounds pretty sweet. I've been waiting for this for quite some time.

Wouldn't this have been awesome if it had really come true?

didnt it? they updated for me on social club & linked me to amazon, but not via personal email...

Ahh, I didn't know it sent it to your email and stuff though! NICE.
