Casting Crowns, Relient K (despite some theological problems in one of their songs), Jars of Clay, one song of Red (Perfect Life), Jeremy Camp, Third Day, Kutless, For King & Country, Matthew West, Michael W. Smith, Matt Redman, Chris Tomlin, TobyMac, Mercyme, and there might be others that I have listened to on the radio but do not know their names. It depends on what you like, my list could get exhaustive, if need be. God bless.
