Iconic lines from Obama’s victory speech are sampled—“They said this day would never come”—and his slogan is co-opted for the chorus—“Yes we can ... change the world”—in Nas’s “Black President.” A driving snare drumbeat marches behind Nas’s raps, which includes lines like, “I think Obama provides hope and challenges minds/Of all races and colors to erase the hate.” Many lyrics require a parental advisory, but the song’s hot-button content is legitimately powerful.
