Simple answer ,not entirely i would imagine , but is there a place for the likes of Dylan ,Paul Simon ,David Bowie, cat stevens etc ...in the commercial songwriting world.
I mean ,i don't think the songwriting ' brains' of the past, rather like great hollywood actors exist anymore......it's rather a rare talent,linked to a particular period of time.
People like Adele write songs for the time we live in,and have a talent of being able to sing benign lyrics in a modern and stylish manner....
It's about the wider public ,being willing and able to embrace some new genius , a wordsmith of extraordinary ability ,and making them mainstream.
