iTunes charts

iTUNES CHARTS: Post-Grammy euphoria continues unabated at digital retail, with performers on the show accounting for six of the Top 10 albums (including the standard and deluxe versions of Babel) half of the Top 10 singles. Pitch Perfect shows no signs of slowing down, as the soundtrack cements its status as a pop cultural touchstone. Ditto for Baauer’s “Harlem Shake,” which has inspired thousands of memes in less than a week, while also unseating longtime chart-topper “Thrift Shop.” Debuting are albums from Hollywood Records up-and-comers R5 and veteran boy band New Kids on the Block, along with singles from 1D and Drake.
