It may be decreasing on iTunes but there are lots of songs decreasing from the top 20 on iTunes, too.
It's still rapidly increasing on radio so I'm sure we'll see a positive effect in the coming month.
Also, this moved up a spot to #27 on iTunes. So, according to half the stans on here,
YESAASSAAAAAAAAAAA IT'S SMASHING ALL HOPE IS FOUND AGAIN SLAY KE$HA
My views towards this have changed so much. I loved it back in November, but the novelty-factor declined rather rapidly. As soon as I heard the album, I realised that it was so bland in comparison to everything else. It's one of the worst tracks from Warrior. A song like this can't sell itself that well. She needs aggressive promotion to make it smash. Please Ke$ha!
