Always a matter of taste and opinion. I like the two above, too.

I like Stan Rogers, early Gordon Lightfoot, Archie Fisher, Leon Rosselson (although I don't always agree with his politics), Lennon/MacCartney, Irving Berlin, early Willie Nelson, John Prine, Jimmie Rodgers (the singing brakeman, can't recall if he is the one with the "d" or not), Hank Williams, Sr., Hoagie Carmichael, James Taylor, Dougie MacLean, Gordon Bok, and whoever wrote the songs on the Simpsons CD my niece has.
