I love anything 60s and 70s rock and roll or soul.
But I'd really enjoy some of the songwriters in the country and Americana genres. Billy Joe Shaver, Jimmy Webb, who wrote some of Glen Campbell's most beautiful songs and the writer of many George Jones top hits, Bobby Braddock who wrote "He Stopped Loving Her Today" which has been voted by Billboard as the #1 country song of all time.
A good Billy Strings documentary wouldn't hurt my feelings one bit either.
