After last week’s unofficial leaks, Rockstar, the creator of Grand Theft Auto 5, has gone on the record confirming the 5th edition its sprawling game with include 15 radio stations, two talk stations, 240 licensed songs, and around 20 movies worth of score music.

Set in Los Santos, a fictional version of LA, GTA 5 is a sprawling metropolis full of self-help gurus, starlets and fading celebrities struggling to stay afloat in an era of economic uncertainty and cheap cable TV. Amidst the turmoil, three very different criminals risk everything in a series of daring and dangerous heists that could set them up for life.

“For this game, which is set in our version of modern-day Los Angeles, what was important for us was to capture that feeling of LA and California,” Rockstar soundtrack supervisor Ivan Pavlovich told Rolling Stone.

“We approached the radio stations as the musical soundscape [created] as you fly into LA. One of the things we’ve never done in a GTA game before is a pop station; exploring that made so much sense in the context of LA.”

GTAV will be the first in the series to have its own original score created with the help of Tangerine Dream and Woody Jackson, the genius behind the soundtracks for Red Dead Redemption and L.A. Noire.

“The score plays during missions, the open-world gameplay, and during online play,” Pavlovich said.

“It’s completely dynamic, and engineered very similar to what we’ve done in the past with our interactive stem system–it responds to what you’re doing with your character.”

Rockstar has unveiled the final trailer for the game, check it out below. Grand Theft Auto 5 launches worldwide September 17 for PS3 & Xbox 360.
