wordy words

Does it sound weird that I have developed a habit of asking myself strange questions while I'm listening to songs?

For example, why can James Blunt say: "My life is brilliant / My love is pure / I saw an angel / Of that I'm sure" while he can also say "Of this I'm sure" but he can't say " Of it I'm sure"?

And how would we understand Savatage differently if instead of saying "Is this the answer to our prayers? / Is this what god has sent? / Please understand this isn't what we meant" they used that?

And why the heck do they keep saying "and all that jazz"?

And why on earth is there a band called "Take That" and there is no one called "Take This"?

And WHY..

Ok.. I'll calm down. Taking a deep breath... I need to listen to something with more music than words. Jazz then. After all, "it don't mean a thing / if you ain't got that swing".. (ehm, what exactly is "that swing"?) ahhh.. :)
