They have 2 duets together, several of their own hits and are engaged in real life, but would Blake Shelton's and Gwen Stefani's songs sound good mashed up? One DJ, who's incredibly talented and obviously has too much time on his hands, decided to mash up Blake's "God's Country" with No Doubt's "Don't Speak" (Gwen was lead vocalist for the group in case you didn't know). People are either LOVING it or HATING it. There' doesn't seem to be a happy middle at all. And Gwen loved it so much that she shared it on her Instagram for all her fans!
