Kendrick Lamar’s “To Pimp A Butterfly” surpasses 500,000 copies sold. 2015’s looking better for big sellers in the record industry than its predecessor. At this point last year, only three albums had gone gold (one of them being Beyoncé), but with Kendrick Lamar’s To Pimp A Butterfly just now surpassing the 500,000-copies-sold benchmark, we’ve already got seven this year. Moving 513,000 units, Lamar joins Drake, Sam Smith, Ed Sheeran, Taylor Swift, Meghan Trainor and “Fifty Shades Of Grey” in the 2015 500,000 club, making this year the fastest we’ve gotten to seven gold-sellers since 2010 (which had eight as of April 11th). Things are, if ever so slightly, looking up for the record industry this year.
