I humbly disagree Jenn. I think his ballards and love songs translate very well today. which is way every generations seems to "discover" him. Some things are timeless. "heartbreak", "unrequited Love", love all are common emotions that have stood the test of times.
As the old saying goes "imitation is the highest form of flattery". I always chuckle when todays supposedly superstars need to come up with a sure fire hit after their well runs dry, what they end up doing is rerecording one of the timeless artist.
