Young Thug, '1017 Thug'
On his first mixtape for Gucci Mane's 1017 Brick Squad crew, Atlanta's Young Thug often comes off as rap's evolutionary endpoint. He raps, yes, but mostly he sings wildly through Autotune. He's part Future, part Lil Wayne, part modern dancehall imp, all ATLien. But the wailing of "Nigeria" or the bonkers "Picacho" (as in the Pokemon character) could only be the work of Young Thug. And he knows it, too. On "Shooting Star" he sings, "I'm a shooting star / just wish away."
