As holiday shopping season gets underway, consider all the devout music fans in your life, in all their myriad splendor: there's Uncle Scott, who still thinks it's 1972, or your nephew who has only ever listened to music on his phone, or Grandma Jean, who could use some nice new headphones to listen to her favorite operas. We have solutions for all of them in our annual gift guide. From books to music to technology to clothes, we'll try to find a little something for everyone.
