Because the song wasn't good enough. She has had enough promo to make up for the video, so the "no video" excuse is invalid at least in the US. Also, look at other songs which smash despite having no video (like Dark Horse right now).
Also, her brand is damaged.
It's the lyrics, "Do what you want with my body". Kids, moms, dads, hipsters, feminists, don't use.
This.
the scrutiny that R.kelly has been through and the GP backlash plus the main theme of the song being sexual and reminiscing of his past not so good behavior doomed the idea of having a music video especially from what we've seen in the leaked screens, it would've had a whole lot of negative attention and gaga doesn't need that right now.
I think the song is too outdated to do well on the charts. That, and her new bad image. And the song wasn't that great overall. Still waiting for Gypsy.
Gaga is associated with EDM-pop. I think this will be the kind of music that the GP will allow her to make sadly. DWUW is outside of her comfort zone so people paid her dust.
