I wouldn't think that because I remember when Hannah Montana was so high on itunes, it blocked Mariah Carey from debuting in the top 10 on the Hot 100
And Hannah Montana is a show which is not the same as Disney playing the music video for like 20 seconds during commercials. HM just had the same effect glee has but just not as huge as glee.
Selena has this big charity concert thing going on in LA later today. Maybe thats what giving her these huge updates? Or maybe Top 10 exposure? Whatever it is- Im happy!
