Dance in the Dark was released as the 4th official single in Australia and it got to #24. That was without a music video though.
So I think DITD could've got to something like maybe #15 in the Hot 100. The general public don't like that sort of music (as we saw with Marry the Night, which Lady Gaga herself has said she based on DITD).
I think it would of flopped. The production is messy and all distorted. It's not that catchy either. In fact, it's one of my least favourite tracks from Gaga. I'm actually surprised to see the positive reaction it's received by posters. But still, I don't think it would've done well.
