Good examples. I make a distiction in my mind between those musicians who criticize our culture, but realize their own frailities, as with Joan Baez, and those who revel in a hatred for everything American which is rooted in a self-loathing I cannot understand. For example, Frank Zappa, who saw America as some kind of diabolical materialistic prison, and seeming to hate most of all those things closest to himself -- his groupies, the R&B music he cut his teeth on, and of course his own self, without mention or apparent awareness that he really, really was full of self-loathing.
The self-loathing Leftist is the most dangerous kind. Joan Baez and Buffy St. Marie, otoh, I would give a hug to if I were to meet them. They are sincere and live what they preach and do it without hating.
