Before then, the music scene was full of great music, songs, songwriters.
I'm not just talking pop music, I'm talking:
Pre 1900 - the great composers - Beethoven, Mozart etc
1920-1940 - the classic songwriters, Gershwin, Porter, Rodgers & Hammerstein etc.
- the great crooners, Sinatra, Tony Bennett
The fifties - the rock 'n' roll revolution, Elvis, Buddy etc.
The sixties - the great explosion of singer/songwriters, Bob Dylan, Don McLean, John Denver
- proliferations of great pop groups, The Beatles, The Rolling Stones, Bread, The Eagles
The seventies - pure pop, Abba
Of course there were some individual standouts after 1979, but not the vast number of quality acts, who are still remembered after some 40 years.
Who will remember Iggy Azalea after 40 minutes?
I just discovered Iggy on Youtube - wish I hadn't.
