The device doesn't always get things right either, but when it does, it's astonishing.
Sometimes (mostly?) your answers can throw it off. I was going for dictionary, but made the mistake of saying Yes to Is it flat? (It wound up guessing Newspaper.)
Yesterday I saw the device do amazing hits, with all different people playing, for computer keyboard, baseball cap, contact lens, the sun, and soda straw. On the other hand, I was not able to get it to recognize Top Hat. (And I very likely screwed up when it asked, Are there any songs about it? and I answered No. There are, of course, songs about top hats.)
