The title is "He Got Better Things for You". It was recorded in 1929 by the Memphis Sanctified Singers.

"I went home and put the Anthology on. I had read somewhere that, in the Fifties, the photographer and film-maker Robert Frank used to listen to the twentieth song on the 'Social Music' discs, the Memphis Sanctified Singers' 1929 'He Got Better Things for You', over and over, as if there didn't need to be any other music in the world. I'd tried to hear something of what he must have heard; I never could. But this day it was all there—as if, again, it had all been obvious.

Smith hadn't credited the singers individually, no doubt because he couldn't find their names. In the supplemental notes to the 1997 reissue by the folklorist Jeff Place, you find them: Bessie Johnson, leading, followed by Melinda Taylor and Sally Sumner, with Will Shade, of the Memphis Jug Band, on guitar. Johnson starts out deliberately, with small, measured steps. 'Kind friends, I want to tell you,' she says in a friendly way. Then her almost mannish vibrato deepens; it's getting rougher, harder, with every pace. When she says 'Jesus Christ, my saviour,' he's hers, not yours. Her throat seems to shred. With that roughness, and the roughness of the words that follow—'He got the Holy Ghost and the fire'—right away it's an angry God that's staring you in the face. Uncle Dave Macon, agent of Satan? This is much scarier. But then, as the first verse is ending, the whole performance, the whole world, seems to drop back, to drop down, to almost take it all back, the threat, the rebuke, the condemnation. Every word is made to stand out starkly, right up to the point of the title phrase. 'He got better things for you'—the phrase seems to slide off Bessie Johnson's tongue, to disappear in the air, leaving only the suggestion that if you listened all the way into this song your life would be completely transformed."

That is from here.
