That's just my guess because May 8th is only the UK release date, and they can't release two songs on the same day in the US so there's either only two songs in the countdown (Judas & MTN) or Judas is coming earlier.
I'm starting to wonder how her singles are going to perform after the album gets released and if she racks up a lot of album sales fast. She has a lot of fans who are willing to buy the album, but will they be willing to buy the album and then extra copies of the singles?
This was way less important back when the Hot 100 was basically all about airplay, but since the advent of the iTunes age charting well on the singles chart is soooo dependent on digital sales. There will always be general public response and those people who only buy singles (refuse to buy albums), but will it be enough to keep her competitive if a potential 2 million sales are already excluded by people already having the album?
TF was able to avoid that problem because the album was such a slow burner, and then the TFM re-release was like pushing the reset button on who had the singles vs. the album.
