Yes, it does make a difference, Georgiansilver. "Jesus Is My Boyfriend" songs are shallow, and promote a shallow spirituality. I think a hymn text should have substance, preferably with roots in Scripture - something that's theologically sound, not just sentimental feelgood music.
A lot of old anthems don't meet the criterion of theological soundness, either. Having a catchy melody just isn't enough.
