It seems they completely forgotten the song 'Questions'. There are 3 versions available on 2 different 12'' singles if i'm not wrong. A couple of edits feature on the 7'' release as well.
All absent from the box.
Anyway, the mastering is better than what's have been available on cd before (apart from The Crunch & Beyond which is more dynamic on the original cd release), all discs have a dynamic range from 10 to 11, which isn't bad in these times.
