Is art more important than, say, designing lifesaving pharmaceuticals? No. Even though I do believe there are days when art will save your life. While I’m sitting at home trying to make a lyric for a song feel less like a crossword puzzle, I know that at that moment there are nursing home carers or social workers or garbage collectors who are doing something more essential than what I am doing. But I confess to hoping that what I am doing may eventually become essential to them.
