The last time Shania Twain released an album - the experimental country-but-not-quite opus "Up!" - it sold 874,000 copies in its first week, and went on to receive the Recording Industry Association of America's diamond certification for 10 million copies sold, her third album in a row to reach that milestone. That was in 2002, right around the peak of the CD age, and an era in which the pop mainstream hadn't yet fully absorbed hip-hop.
