What music have you been listening to lately? What have you discovered, what speaks to you these days?

My iPod now has about 2,000 songs, and it is a source of great pleasure to me. I am probably still more heavily weighted toward the music of my childhood than I am the new stuff. There’s still a lot of Stevie Wonder, a lot of Bob Dylan, a lot of Rolling Stones, a lot of R&B, a lot of Miles Davis and John Coltrane. Those are the old standards.

A lot of classical music. I’m not a big opera buff in terms of going to opera, but there are days where Maria Callas is exactly what I need.

Thanks to Reggie [Love, the president's personal aide], my rap palate has greatly improved. Jay-Z used to be sort of what predominated, but now I’ve got a little Nas and a little Lil Wayne and some other stuff, but I would not claim to be an expert. Malia and Sasha are now getting old enough to where they start hipping me to things. Music is still a great source of joy and occasional solace in the midst of what can be some difficult days.
