The song just got It's 2 biggest updates on radio since the release week and haven't gotten red update on Itunes for 2-3 days .. You do realize that If raido played the song more It'd be selling even more ?
And the logic of some of you

So the song can stay in top 5 on Itunes for 1 year but since It's not selling half of the number 1 song It doesn't have longevity ?
