Rod Stewart's raspy voice didn't exactly make him a shoo-in to become the ambassador for the Great American Songbook. But maybe that's what makes his interpretations so interesting and appealing: The way he reimagines jazzy standards like the “The Way You Look Tonight” with sweet, loving vulnerability (which couldn't sound less like Sinatra's tough-guy croon). His quivering reach on “These Foolish Things.” The playfully rough-around-the-edges rendition of “As Time Goes By” with Queen Latifah. These songs have been covered millions of times—even by hundreds of greats—yet Stewart still finds something new in each of them, and makes them even more approachable with warmth and sincerity you can feel.
