Thanks for the great feedback, guys.
@Trent: Yes, on this website, it makes sense to put adsense at the bottom.
@Zac: Thank you for checking out the website. Glad you like it. I'm improving, eh?!
@Evan: (1) Ah yes, you spotted the stock image! Thank you for the offer. I will get back to you in due course... (2) Thanks for pointing out that iTunes came up in Japanese. I forgot about that being likely to happen. (3) I agree the intro was far too long; I was indulging my excitement at producing my first bit of Garageband muzac without using jingles!
Next one should be out tomorrow... but I haven't finished recording it yet, let alone editing it.
