Today is T.I.'s 37th birthday. We celebrate by revisiting the three albums that constitute his creative prime: Trap Muzik (2003), Urban Legend (2004), and King (2006). These albums are significant because they represent the formal origination, evolution, and coronation of trap music. And while while Gucci Mane and Jeezy were instrumental in the subgenre's popularization, T.I. sees himself as the true inventor of trap.

"Whose album was Trap Muzik?" he asked in an interview with Montreality. "Who had an album named Trap Muzik? I'm asking. Well than that's who started it. It's as simple as that. Unless you can think of a time before then that you can recall hearing it. I mean, since it was introduced to the world, there were people who came on and enforced and spread the genre out and gave it wings and life beyond its origin. But if you go back to who truly started it, I must humbly say myself."
