Outside the US, possibly. I think it's a dumb single choice when you have Doubke Rainbow, Legendary Lovers, International Smile and Birthday on your album.
Absolutely.
All of the hype for PRISM and her singles seem very front loaded. I think she'll see an exponential decrease in sales and chart performance after the holidays.
it could be heavily front loaded and peak digitally before it does on airplay, but I don't think it will flop personally...ANY single can flop, in theory
