Imagine Dragons' "Demons" looks like it will be their third multi-format hit in a row. It went to #1 at Alternative, nabbed a HitPredictor at Top 40 last week, and is a HitPredictor at Hot AC this week. Meanwhile, Avicii has his first multi-format U.S. smash with "Wake Me Up." It's already been a HitPredictor at Top 40 and Hot AC. Alternative, which usually leads the way on new artists, follows this time, as Avicii scores an Alternative HitPredictor this week.
