Grand Theft Auto IV is not all about the game, it’s about the music too. Rockstar’s latest creation includes over 200 music tracks that can be purchased directly from the Amazon.com online music store thanks to a feature of the game that allows players to tag a song, find out more about it and buy it.

Music labels couldn’t be happier: the game’s success could turn into a music industry success, as many players are likely to purchase some of their favorite tracks in the game, with just a touch of a button (yes, there is a buy button).

“It’s a very big deal for us,” said Cynthia Sexton, senior vice president of marketing and licensing for EMI Music North America, according to Reuters. “We’re continually looking for new ways to sell our music. There are millions of people buying ‘Grand Theft Auto,’ and we hope they will enjoy the music and in turn buy those tracks.”

The conclusion: the combination couldn’t do better than that, for both Rockstar and music labels. As Ivan Pavlovich, the man behind Grand Theft Auto IV’s soundtrack, told MTV in an interview, he had to pick the best songs out of a total of 850 tracks (214 of them remained).

Licensing them was the hardest part, as he had to speak with over 2,000 right owners, and hide the reasons he wanted the songs for. There was a not so pleasant side to the whole deal however, Pavlovich unveiled, as some of the right owners have asked for free copies of the game (usually more than one).

Grand Theft Auto IV is a complex story, and producer Leslie Benzies confirmed a budget investment of $100 million in Rockstar’s latest title. According to Benzies, approximately 1,000 people have worked on the game over the past three and a half years.
