3 was in the top ten for months, and that is with ZERO promotion. And sold 2 million in downnloads (In the US alone) . It also was a smash on radio hitting #2 on mediabase and having the highest debut for an any artist on the World Chart, coming in at #2. Again, this is all with zero promotion. Most artists promote the hell out of their singles to try and get the same success but Britney did it without lifting a finger. 3 was a smash hit. End of story.
