Grey's Anatomy has an interesting history of using Christian artists in their show. While the show is questionable at best for believers, it's nice to see this music being exposed to the masses. Some artists are crossover such as Lifehouse and The Fray while other are decidedly not such as Caedmon's Call and Katie Herzig.
