How to see how much music do I have in iTunes? The new iTunes version has brought some changes. And I just realized that it won't show anymore how much music do I have.

It used to say the size and the total play time at the bottom of the window, but it's gone now. Can I ripristinate the indicator? Or what's the easiest way to check my music library size?
You can bring back those details at the bottom of the screen by clicking Show Status Bar in the View menu, or pressing ⌘/.
