I relate more to the descendants of Galileo Galilei and the Wright brothers than I do to anyone else you might mention. If you could name someone working today who I could relate to, I'd be both surprised and thrilled.
The songs I write should only be gauged by what other writers or peers are doing today. If the barometer for all songwriters was to match his body of work, then anyone you might mention alive or dead is a failure. But I've learned to not be too hung up on what's fair or not fair.
