It wasn't a surprise album, everybody knew the album was coming, they just didn't know the exact date, bayonce leaked photos at video shootings, leaked bow down, the tour, super bowl, lip sync scandal, it was one of the most promoted projects ever. It's not like she came out of nowhere and released the album, she was everywhere. If she promotes now and starts doing interviews, it will be overkill, plus the album doesn’t have a smash hit, there’s nothing worth the promotion.
