With all due respect, this sounds like a comment from someone who's not really into music.
I did a quick check with a musical friend to see if he shared my initial reaction... "what's your favourite song?" resulted in "I have no idea how to answer that question. Maybe ask me my top 100 favourites?"
I'm well over that age now, and I have a new "favourite song" every week or two. Easing into more free time as the kids get older and am using some of that to go see more live music from local bands.
