Flan,

Nice song and Christian message. I mean this kindly - most people have short attention spans and over 8 min outside of a real church service is long. If you do another one I'd make it more the length of a regular song 3:30 to 5:00 mins tops.

My suggestion is to put the lyrics in your description since the vocals are somewhat back in the mix. Plus it would be nice to be able to read them and it would reinforce your message.
