All the fussin' & criticism that goes on here can get ridiculous! After Ray Charles died, I recall hearing one "bigtime" (in his own mind) critic saying that everything after the Country album was all alike. Why dance on his grave? Why speak ill of the dead?
Does this make you feel more important?
Each Musician has their own style. Some change their style over time, some don't. Some Musicians do something besides sing & play Music.
I remember seeing recordings of John Denver in the far east back in the mid 70's. When a Musician's Music is known on the other side of the planet in completely different cultures, has a song on a Beatle!! album & is recorded by many other artists, is one of the first Musicians to perform in the former USSR, was out beating the drum before "we are the world," has the respect of Jaques Cousteau, not to mention influence many, many people to play the Guitar in the fingerpicking style--there must be a reason.
Oh yeah, & he was a fingerpicker--he played acoustic Music.
