iTUNES CHART SNAPSHOT: “All About That Bass,” the female self-empowerment anthem from Epic newcomer Meghan Trainor, has powered its way through some heavy traffic—namely, Nicki, Ariana and Jessie—to sieve the top spot on the singles chart. Looking at albums, Marvel/Disney’s Guardians of the Galaxy: Awesome Mix, Vol. 1 continues to hold off all challengers in its second week, and Republic’s Godsmack takes #2 from Loma Vista’s Spoon.
