Taylor Swift

So for the past 2 weeks on a Monday, Taylor has been releasing 30 second previews of a new single on Good Morning America. Since this show comes on early in the morning on a week day, I'm usually at school so I miss it. (i usually watch later in my computer class in 4th period) but this week, since it's Columbus Day, most schools are on a holiday, I get to watch it! Whoo! The only bad thing is that I'll have to set my alarm to wake me up early so I won't miss it. Does anyone know how many minutes after the show starts, it comes on? Because I think for the first 30 minutes, it's just news.
