So apparently Applause add date is 8.20 which is Tuesday ...
This is Interscope promo page:

It says:


Does It have a bigger chance at debuting at number 1 or even with a day airplay It will still debute on hot 100 Or maybe It will still have a huge airplay on Monday without being added ? It's really weird that the add date is 1 day after the release :X

Now we have the Song and the Video on monday and the next day radio release It's really Interesting .. wonder what is their strategy etc. . .

It depends on when Katy's single is released and whether or not they'll go head to head in their first week.

I don't think add dates matter can't radio stations start spinning a track as soon as it's in release?

I am wondering that as well cuz some stations played (I don't really remember If It was BTW or Judas or TEOG) a song every hour (like a radio deal) but without having a radio deal If that makes sense.. IDC If It debutes at number 1 or skyrockets the next week It's just Interesting that the add date is not monday .. there is no point
