Anyone who knows me knows how important music has been to me since I was knee-high to a record player. From embarrassing Cliff Richard impersonations as a five-year-old (apparently “Summer Holiday” was a family crowd-pleaser) to the eclectic cast of thousands on my iPod, music has been a constant thread throughout my life. So as I approached my 50th birthday last September, I figured why not “do a Nick Hornby” and pick out 50 songs that have meant the most to me over the past half a century. I finally got around to finishing it over Christmas.
