"Letter 2 my Unborn" was this great song that captured what he really wanted to say to all the fans, not just his unborn child I think. I'm what I call an "after-death" fan, and for that song, it was like Unborn Child could also mean "Unborn Fan" or undiscovered fan, and if you listen to the song that way u can see it can be literal.
Happy Home is real good too.
