I bet I can guess each poster in this thread's age by their choices
some of my picks for best songwriters:
beatles
pink floyd
simon & garfunkel
joni mitchell
elton john (though i'm not sure how much of his work he wrote)
I'm not necessarily a huge fan of any of the aforementioned artists, but I do respect their songwriting abilities.
Not trying to hijack this thread, but music producers are just as if not more important to music recorded in the last 40 years thank the songwriters.
