Spotted: Decoded by Shawn "Jay-Z" Carter

Where: D.C. Metro, red line
Who was reading: A woman with a sensible haircut and an even more sensible gold earring. Presumably there were 2 earrings, but I only saw her in profile.

And what's the deal with that book? It's sort of a memoir and sort of a concordance of Jay-Z's lyrics, unpacking the wordplay, symbolism, and allusions to real-life events.

Do you have a favorite Jay-Z song? Probably D'Evils or Regrets, both from the album "Reasonable Doubt." Because they're both so sad, you know? I guess I'd give the edge to "Regrets"; it has a more interesting beat.
