Why does Pandora keep feeding me “Layla,” even though I’ve told it three or four times that I don’t want to hear that song? Apparently it has many different versions to offer and figures “You didn’t like those three? Then you’re sure to like this one.”
Along the same lines, it is convinced I’m a Jack Johnson fan no matter how many of his tunes I reject.
I think those genomes could use a little more tinkering.
