It's easy to dismiss today's pop-music as simplistic and look up to Wagners and Mozarts of the past. However, 200 years ago, most of the western worlds population never heard an opera and the music they were playing/singing and listening to was just as simplistic. A typical tune, like Pastime with Good Company was nowhere near the complexity of the Ride of the Valkyries
On the other hand, there is still a lot of serious music being made now-days that is being listened to by a minority, just like before.
"Pastime with Good Company" is a lot older than 200 years. It's attributed to King Henry VIII (which could well mean that one of his court musicians n2helped" him with it).
Money can't buy love, but it improves your bargaining position. -- Christopher Marlowe
