I grew up with hymns because the denomination I grew up in believed any contemporary music was literally evil, so modern Christian music was quite the discovery.
I tend to like Casting Crowns (very solid scripture base). And stuff like Skillet, though Skillet and some similar bands are probably best described as "music that is just written by people who happen to be Christians", most of the time. Disciple is good and also heavy scripture base. I also like some stuff by Hillsong and Bethel, though I understand some of the theology of the people behind the bands is rather wacky.
Relient K has a few good Christian songs, too, and probably my favorite band overall. Deathbed and Those Words Are Not Enough are examples of songs by them with heavy Christian themes.
My general music taste actually tends to gear towards hard rock. (Which is why Skillet's older stuff and Disciple and some others appeal to me.) But so far as worship music goes I just listen to whatever.
