"You're not making Christianity better, you're just making rock and roll worse" -H. Hill.
Edit: Also the bit with the rocker's dad about the fifth commandment.
There are Christian artists I've really enjoyed. Iona spring immediately to mind, although I haven't listened to them regularly in years, but the relevant points are:
1) Their lyrics tend to have more substance to them.
2) Even if the style isn't your cup of tea, there's some real and undeniable musicianship on display.
Although way poppier, and with edgier lyrics, I'd probably put Switchfoot in the same category.
You would probably also appreciate Jon Foreman's (Switchfoot founder) solo work too.
