Knowing how much money Nicki’s fee would have been for the first single they definitely won’t sink as much money for a second single (although there’s a rumour Jesy fronted some of Nicki’s fee herself).It's really not in her favour that there isn't a follow-up single yet, and that it appears there was no follow-up recorded at the time of release. It makes me think they were testing the waters, albeit with a very expensive, throw everything at it attempt.
The memeing and outrage media may have bought her enough attention for more attempts, but I'm not sure they'll sink as much money in for a second try.
