First of all, I love this post...
Christian music does two things for me. One is it makes me feel great when I hear it. Christian music can bring two people together in a way that is very different from other genres because of the way that God works through these artists. A person can tell the difference between an artist inspired by the industry and one who is inspired by God.
The other thing that christian music does for me is it is the enlightenment I need to begin my day and it is the encouragement I need to continue through the day. When you work around people who are living their lives outside of the will of God, it's easy to fall into a trap and stray off of the path God has for you. Christian music helps to keep me encouraged and is the reminder I need that what I'm doing, as a Christian, is right.
So, while other genres may be inspiring, enlightening, or encouraging, Christian music can be all of these things not only for general life experience but can also keep a person on the path to righteousness.
I know I'm not the model Christian, but through Christian music, God speaks to me and keeps me on the right path. So, that's the reason why I listen to Christian music.
