Music for the ages

I've been having dance parties with my 3-year-old daughter a lot recently. It's one of our favorite activities. A lot of my music curation now comes down to finding music that she might like that I might not hate. Her top jams are "For the First Time In Forever" and "Let It Go" from Frozen, although she loves the whole soundtrack (except the scary non-singing parts). We also introduced her to the Sound of Music and Annie, and "Shake It Off" has become a staple. Recently I dug through some Beatles songs on Spotify to find some that might be especially good for a toddler. I came up with "Good Day Sunshine," "Here Comes the Sun," and "Ticket to Ride."

The Beatles broke up over fifty years ago. I wonder how long their music will continue to resonate to people, and what that will be like. This idea of commercial recorded popular music is relatively new, and I am curious how it will go down in history. I mean, people still love classical music and songs from hundreds of years ago, but you don't hear The St. Petersburg Symphony's 1867 recording of "Waltz of the Sugarplum Fairies." Will the rock music my parents grew up with start to sound dated and run out of favor at some point? Will kids still be getting turned on to Zepplin and Pink Floyd and The Clash and Operation Ivy and Tribe Called Quest 50 years from now?

This has been deep thoughts from an old man.
