Of course Nigel and Johnnie.c are correct. By the time you comb through age and cultural filters, you would NEVER get a consensus. Plus, there are other factors. I love the era that produced 'Bird', Miles, Monk, Dizzy, etc., but many of the tunes that propelled them to greatness (now called 'standards') were written a decade or two earlier. I think Johnnie.c put it best; "We all have many great memories and I think that is what makes music not only unique but persona". I agree 100% (although the Bebop era WAS the best ).
