If you're 65 then you lived through a whole lot of musical eras. the 50s music, The English onslaught the BEATLES STONES KINKS DONOVAN years The mellow folk singer era with Joni, Cat Stevens, James Taylor, Crosby Stills and Nash etc. DISCO

NEW WAVE Flock of Seagulls Duran Duran,etc. Reggae, All that stuff and more
Think of how much you have to draw on.
Some people get stuck in one era and never leave
Today 17 year old is in tune with their era and have a whole lot more musical tools at their disposal....making it easy to sound today modern
While we would all like to write hits that the world would sing and buy, I think that you would be writing no matter what. Making something out of nothing.
Mix up a hip hop beat with a folk song,
Most of all have fun being a songwriter
