Duration of Tracks & Albums AND Description

I am unable to view the duration for any tracks nor for the album.

When adding tracks and albums, there is no place to enter the track duration nor the album duration. The duration of the album is not editable from the Admin page. I see you have the duration for your tunes and album on your web site.

Also, I’d like to be able to add a description to the album and/or the track. Is there a way to do this as well when uploading tracks and albums? I am not fluent in JavaScript yet, but can hunt and peck.
