I agree with the others that as presented, it all sounds boring and too scripted. That is not how people sound when they are having a normal discussion.
Music: fine
Voices and Tone: See above
Content: Easy to follow so far
Does the content make sense: You certainly made it clear what your objectives are and those objectives make sense. However, Luke says:
"So, I want to be very careful to figure out what really is better rather than what is better according to my own tradition or what appeals to my own psychology." (emphasis added)
Even as a Christian, I would be interested in seeing how you intend to go about figuring this out starting with naturalistic presuppositions. Frankly, I don't think it can be done without someone being able to rationally charge that whatever you decide is either "according to your own tradition" or "apeals to your own psychology". But maybe that is just because my head is buried in contemporary moral philosophy, as you put it.
Be that as it may...I would listen (at least initially).
Length: I think the length is good.
