Granted. You get an extra hour of the day in which nobody can access, but then the time gets stuck and you somehow explode of depression because you can't acsess new things and you can't see anybody. That sounds bad.
Granted. Nelly will outsell 21, but she will have ads all over McDonald's, and is forced to make a childish cover. To sell it, there is ads on the McDonalds and Burger King bags. There will be a special meal with her album and chicken nuggets for $3 because it can't sell. In the long run, it sells 1 more copies than 21 in packages of McDonalds.
