A myth that is perpetrated by the simple fact that people tend to only remember the good music and forget all the crap. Radio stations also only play the good music from the past, not the crap. Since we forget about the crap, music from the past has the illusion of being better. There were lots of really crappy songs in the 50's and 60's, but you never hear them anymore. No one will remember The Spice Girls in 2027.
