It'll be released the same week that Gaga (and Naughty Boy feat Emeli Sandé / Ellie Goulding) is releasing her single
It'll be a tough fight, then. I suppose Naughty Boy will probably win, since he's got Emeli Sande. Then Gaga will debut and peak at 2, since she's supposedly not repressing the single for airplay promotion like she should.
Then Safe and Sound (which could easily contend for 2 as well), then Burn.
