Not easy to answer this one ened.
If you have things in the library and select songs then the full list should appear including times.
If I choose album then across the top appears things like, album, count, length. If you click on say length it will tell you how long the album is and count will tell you how many tracks there are.
I have not checked but I assume if I put a CD or DVD in the same choices will become available.
It's not obvious I agree and earlier versions of media player seemed easier to follow.
