It's not surprising that Taylor Swift has a double HitPredictor this week with "Shake It Off" at both Top 40 and Hot AC, considering her record-breaking debuts. Meanwhile, Nicki Minaj, Matt Nathanson and Mary Lambert each earn their second HitPredictors. Mary's "Secrets" earned it last week at Top 40 and this week at Mainstream AC. Nicki's "Anaconda" nabbed it 2 weeks ago at Top 40 and this week at Rhythmic. Matt's "Headphones" won July 14 at Hot AC and this week at Mainstream AC.
