Many thanks to all who have responded. @jsalerno277 Yes - I was looking for subjective opinions - I like your choices of works by period.
What is interesting is that though the genre is known as "classical" very few of the iconic pieces are from the classical period! I think the only classical works mentioned are by Mozart and one by Haydn.
I had wondered whether there would be much mention of early / medieval / renaissance music - I listen frequently to my collection of Archiv recordings - Ockeghem, Josquin et al. but the only pre-baroque piece in the list is by Hildegard von Bingen - some 300 years earlier than my renaissance listening.
Beethoven symphonies and late quartets appearing often was no surprise.
Over the next few weeks I shall listen to all of the works that have been mentioned - and perhaps explore the late 20th century.
It is wonderful how streaming (especially Presto) makes exploration feasible.
