1000: "Life Of A G"
From the first song on his first tape, Future was letting us know that he'd be something different in the game. The year was 2010, and auto-tune was still most associated with T-Pain, Kanye West, and Lil Wayne, all of whom used it for purposes far removed from street rap (remember, this was the same year Weezy dropped Rebirth). Here comes Future rapping bars that you could envision coming out of Jeezy's mouth, and yet he's doing it with melody, even before the huge chorus hits.
"Life Of A G" represents the midpoint of 1000, which splits its time between R&B cuts like "Good Look" and "Stop Playing," and the respective Jeezy and Gucci Mane homages "Do It To Em" and "Yeah Yeah." On it, you'll find themes that continue to define Future's music: paranoia and the connection between his drug use and prolific output ("I go blank-eyed in the studio and try to fuck up my kidneys"). On top of that, it manages to contain two separate hooks, hinting at the level of songwriting Future was capable of from day one.
