Christian music and Christmas music have a very similar feel as if they should belong under the same type of music, (speed, how they are sung, the continuous amount of declaration of love of God) but they are sorely different.
I don’t like Christmas music, and I very much enjoy Christian music (even when I was strictly Agnostic).
Christian music is about love, and devotion. You can hear it in their voices. It’s not about the religious aspect for me, but rather the emotion itself.
Christmas music has a little bi of s selfish twist that makes me personally not enjoy it. It is about one’s own love of the feelings of the time. Love of the day as a gift from God (Christmas music is still rather religious)- love of the day as a gift, not love of someone else. Love of what is being provided to them.
Just my thoughts, thanks!
