Gary Clarke Jr. Has some good protest songs, especially for a blues musician, including a remake of Crosby, Stills, Nash, and Young’s Ohio.
Municipal Waste is great for some hardcore, there’s actually a bunch of hardcore bands that have some excellent protest songs.
Then you have Ice-T’s Body Count.
Lamb of God’s albums post-Randy’s time in a Czech prison have been full of social commentary, far more than the earlier albums.
I’ve seen people highlight Killer Mike’s Grammy wins, but his other group Run the Jewels is pretty much the biggest name in protest rap these days.
Then you have Kendrick Lamar, possibly the best rapper of his generation, absolutely one of the greatest story tellers of rap, period.
Overall there’s a lot of pop, metal, rock, rap and other genres who have some prominent names and many lesser known names who are putting out good angry music.
Then you have Ice Cube putting out Arrest the President then proceeding to talk about voting for that same president.🤦♂️
