The indie engines that could—Macklemore & Ryan Lewis and Baauer—are looking down at the field from their present perches at the top of the sales chart. While “Thrift Shop” slipped by 12% after breaking 400k a week earlier, “Harlem Shake” grew by 13%, so their positions could conceivably be reserved on next week’s chart. Bruno Mars’ latest single was up 6%, moving it up a slot to #3, while One Direction entered the Top 10 in its second week behind a 16% jump from #16.
