It would be a lie to say music hasn't changed over the years. Music has been around for thousands of years, so it wouldn't be much of a stretch to say that music has progressed alongside humanity. From the invention of new instruments, to different geographical locations and influences on musical creators around the world, there is endless explanations. Obviously the usual track beat with someone singing their stereotypical lyrics is vastly different from the bum playing the lute at the local bar from medieval times, right? They may come off as different music types from different times, but many of the factors that made music enjoyable to listen to then have carried over into today's music.
You would be pressed to find somebody nowadays who consistently listens to 60s music, yet was raised in today's progressively advancing world. But that doesn't mean 60s music has different meanings to today's pop music. If you try to find the purpose the writers from both genres try to pursue, they actually line up very well. This can be presented through countless different ways, such as lyrics. Lyrics oftentimes are the most direct way of getting the purpose of a song out there, as the writer can literally state their intents. Obviously this can be wrapped up in the songwriter's own special way, and the literacy used has changed from the 60s to present day, but the motives stay the same. Love songs back then compared to loves songs from today are still talking about the same feelings the writers felt. Another great example of this is chord progressions. The feeling that actually makes songs feel either really happy or sad is nothing more than a few basic notes in a cleverly arranged order. Creating these emotions has been in music since the very beginning, as the whole point of music is to evoke something within the listener. Many songs from different times might share the same chord progressions as songs written today. This shows that writers from different times often pursue the same emotions that chords create.
At the end of the day, music has obviously advanced in a countless aspects, and it would be pretty hard to force someone from today's world to try and consistently listen to and enjoy older music. But many people don't realize that the core characteristics of music have mostly stayed the same throughout centuries of musical evolution. It's what allows music to communicate to people in personalized ways. Although music will almost definitely sound different in one hundred years from now, it will still evoke feelings and emotions that people have always felt.
