Truly mortifying. There's just no excuse that is believable for Martha. If anyone was in charge of her career (oh--wait...), they would've made sure everything was flawless--especially because it's a hard song to sing AND so many others have also botched it. This will likely drive away some people who might (MIGHT!) have checked out her new single (of which I'm not really a fan).
If you really want to pour salt in the wound, try listening to it at .35 speed... ALLLLLL the way through. I mean, oh... uh... WOW. Try it for even 20 seconds. Wow.
