Well, if 4 CD's is 1600, presumably 1600 is MDC, which is the requisite 3 letters long but it doesn't mean anything to me.

One of my favourite crossword clue of all time (I think it's an Araucaria) is:

HIJKLMNO (5).

I may have mentioned to oldtimers before, in which case perhaps some of our newer members would like to have a go.
