The only competition Katy will have looks to be LMFAO (On Billboard)
The Edge of Glory is not going to hit #1
Agree that 70% chance it won't hit #1, but TEOG will be a #2 contender on Hot 100 for sure, its video will help the song explode along with AI and airplay!
So exciting! Do we know what is causing this sudden increase?!
i know, that lot of people would say because of dating with the Bieber guy, but she had a lot of promo, and she will have more...
On this week she’s scheduled to do more than 30 interviews and sing on Good Morning America (ABC), and weekend she will co-host the Much Music Awards in Canada...
But she has to rest because her illness, but she cant, she couldnt never... always the work! : )

Yessssss. Lets go Katy. Gaining over 5 percentage points in one update and Nicki Gaining around 2 percent.
As someone said Katy's gaining over 2-3 or even more in every update! She is over 81% right now, so I think she would top iTunes in 2 days! When the AI would be high she would climb at #1 on Hot 100! Lady Gaga can be a threat but we have seen that Judas video (which was really catchy) didn't work so much and I believe that TEOG video would push her but not so much! Katy's team can make this hype everytime before the her songs are released and she is rocketing because of this! But when all this hype goes she has this longevity that makes me sick! Every song of hers spent more than 15 weeks inside the Top10 and her Radio Support is just unprecedented! 4 #1 and a 5th to go!
When it seems that he'll FINALLY pass Adele, Katy will pass them both.
