It IS strange when I went back to watch that song from SB's apartment is the one playing numerous times during scenes on the cylon base ship.

But there also is another consideration that perhaps the song wasn't created or played BY SB's father but maybe it was a favorite of his. But I do think the dialogue implies that it was SB's father who created or played the song.

This could be a hint after all that maybe Starbuck is the Final Cylon. Is it possible they made it too obvious to become unobvious? Like, we all automatically think they are implying she is a cylon so we dismiss it because it's too heavy-handed.

Her being the first cylon hybrid is not really plausible to me. I mean, the show has flat out stated the first hybrid was the thing from Razor - and it was in a tub and half human hooked up to wires. And why all the buzz about Hera then? In this premise, I can only see it as maybe Starbuck is the first human cylon hybrid created by the Hybrid from Razor (which would be why the regular skin jobs don't know about her). But I still think it's not true.
