Golden

In 2004, he bought the house that he's living in now and also stated the Water Dissolves Water blog.  It was 10 years ago, and he turned 50 that year.

Despite the constant tension in Corsica and Florence the year before, they traveled together again the next year (2004), this time to Budapest, where they missed the Beastie Boys by a week, but apparently managed to catch some busking violinist instead.

He was still listening to KCRW in 2004, who were playing a seemingly endless series of remixes of Jill Scott's neo-soul hit, Golden, that year.  So for lack of anything else that he can recall, the song for 2004, the Golden Anniversary of his life, is Jill Scott's Golden.
