Yeah, I became confused. I saw that it said "Shota's Lullaby" was written and produced for this episode (and I didn't click on the link that would take me to YouTube for any of the other songs after that), but then I just had to click on the link to YouTube to find out who was/is behind Cara's song. Seeing that the song has actually been out for some time confused me, and made me forget about "Shota's Lullaby" being specifically written for this episode. And, well, you just told me that the others (with that one exception) were as well.

Thanks. I was hoping someone would clarify. Although, my lazy self could have just clicked on all the other YouTube links to answer my questions on that front.
