If you ignore the auto-tune yapping, this Thank God For Drugs era Kanye West leak seems to sample a soul song of some sort. I wasn't able to Shazam it (even slowed down) and Google didn't come up with anything either, both when searching the lyrics and the title of the song.

>Artist: Kanye West
>Title: "Immitation of Christ"
>Era: Thank God For Drugs / Yeezus
>2010s
