I've had very eclectic tastes since childhood. As Emerson said "A foolish consistency is the hobgoblin of little minds". I loved, and still do love, really loud rock music such as Yuri was fond of including his beloved Mountain with Leslie West. I also have always loved folk music including Melanie mentioned above. I love the Blues such as Muddy Waters, Johnny Winter, BB King, etc.
Due to exposure from my daughter's radio stations I am now a big fan of Shakira and Amy Winehouse.
And I am the world's biggest POCO fan, their 1969-1977 output up until Tim B. Schmit left to join The Eagles. Eagles #2 as far as country rock.
Then it gets a little strange, LOL. As far as Male performers go, as Borderstone likes to break it down, my top three would be Lightfoot, Donovan, Frank Sinatra.
But from the first time I realized who Lightfoot was and then bought that Don Quixote album in 1972 he has been Numero Uno. A man's man for the men and a lady's man for the ladies. And I had a beard and jacket just like on the cover. Second Cup Of Coffee is the soundtrack always playing in the background of my life, LOL.
That's my take on your question B - very thought provoking. Good topic.
