Playlist total time and selection total time

Sometimes we just need to know that we have enough music of a certain type or kind, so add the total time in the summary bar where the playlist info is shown
example
Playlist Name (337 Tracks) {28.08 hours / 1685 minutes }
Or something similar
Also, when you have tracks selected, it would be awesome if the selection had the same info.
So in the same line as before where playlist info is (possibly centered cause there seems to be plenty of room), add
Selection (23 Tracks) { 1.92 hours / 115 minutes }
example
