I love well-executed classical music, and certainly don't mind sitting through it at church - but what stirs me, and seems to speak to me, is the music I identify with (which for me is R&B). Maybe the difference between me and some other people is that as long as it's well-executed, I am happy to hear anything in church, knowing that it's ministering to someone. Maybe it's not me that time...but maybe next time it will be. Whatever is done well and glorifies the Lord is a good thing, imo.
In my opinion, it is too - it's wonderful to see talented people use that talent to further spread the Word of God - that's what it's all about, after all.
