I think Marry The Night's doing relatively well here in the US. Sure, she's had to promote it a hell lot, but after the momentum she lost with Y&I, a little reluctance is expected. Plus it's getting really great updates on radio.
If anything, it's the UK chart performance i'm worried about. It STILL hasn't cracked the Top 10 despite all the promo she's done there.
Still hope for the best, though.
