Hey, Nick :) Am enjoying the daily update from each of your 100! If you’re keen to look further into the question of how musical tastes change with age, I’d recommend this book: http://www.amazon.com/This-Your-Brain-Music-Understanding-ebook/dp/B00556G7R4/ref=sr_1_1?s=books&ie=UTF8&qid=1437950626&sr=1-1&keywords=this+is+your+brain+on+music

Keen to hear your thoughts on it, if it finds its way onto your shelf! In the meantime, all the best for your daily writings, and for new fatherhood!
