A MUSEUM QUESTION!

[Diana]

OK, just shoot me if someone asked that before, but I`m too tired to search. 12:42 a.m. x_x
So... I`m asking: A Museum is 30 single collection,right? Well, I`m too lazy to watch the whole thing again so I went on wikipedia and there are 24 songs! And... Why is it 30 single collection if she didn`t sing all of them!? ... not fair Counting on you guys to tell me... It has to be a good reason (or not).
