If I didn't know anything about Paul Krugman, I think I'd still love him for his music postings. Not so much for his particular taste in music and/or performers, but for his guts and creativity and uniqueness is posting musical choices. Here's his "Friday Night Music: Ten Favorites" from this week.
But if it wasn't this, it would be something else equally creative, unique, interesting, captivating. I believe Krugman is one of the leading intellectual/social/political and of course economic lights of our era; you should be reading him and his blog regularly.
Please ask me if you need help in setting up an "RSS Feed" to get his postings—three or four a day, normally—automatically posted in a place where you can conveniently read them.
