What is Authentic Orthodox Music?

"Just wanted to let you know that because of AFR, and especially the Our Life In Christ series, I am becoming Orthodox. A parish is building a new church near me and have put out a sign. I've been a Protestant for years, and when I saw the sign realized I didn't know much about Orthodoxy. I Googled it, read a bit, and was intrigued. So then I found AFR and started listening. I now listen to it every day on my drive to and from work. My knowledge and understanding of Christ has grown so much over the past six months. I have now started regularly attending a local parish and meeting with the priest. God bless you."
