As the guy who writes The Number Ones, I’ve lately heard from a lot of people that the column has given them a new appreciation of Janet Jackson. If I accomplish nothing else on this planet, I’ll still feel pretty good about that. Janet Jackson had one of the all-time great pop-star runs, and she should not be taken for granted. Next year, the world will get a chance to revel in that songbook once again, as Janet is heading out on tour.
