I love his music, voice included, but if you don’t like the voice please listen to the early stuff before he got so rough. I honestly like those records better. The Asylum Years album collects a bunch of the good ones. ETA - or Ol’55 I think has so many good ones, including the namesake song.
Off topic but I watched him play piano and sing on some late night show a long time ago and oh boy did he look like he was on heroin, nodding off.
