If you have an iPhone, you've probably noticed the new(ish) autocomplete feature: when entering text, iOS8 gives you three choices for a possible next word in the sentence. (And yes, if you have an Android phone you've had this feature for like, ever.) If you keep on pressing the middle button you'll get a sentence that is syntactically correct but largely content-free. For me (and others), it's "The only thing that would have to go back and I don't think that is was not immediately known", but it apparently depends on your writing history.
Later in the song he uses other buttons than the middle one, but it's impressive how he keeps the taps up with the words in the song!
That's all from us this week. See you on Friday, and have a good weekend!
