He has a lot of good originals, but I also love his covers (e.g., brown eyed hansom man, don't think twice it's alright). He is one of the few artists that got better as he aged. His stuff from when he was younger was a little pretentious, but as he got older and had real life experience he became an all-timer (also happens to be when he got into the outlaw country movement). Not great vocals, but sincere sounding.
