So sehr ich das Konzept vom ÖR gerade was Nachrichten angeht auch wertschätze im Status Quo (auf jeden Fall besser als Nachrichten als Marktware), es ist kein Geheimnis, dass sie sich oft schon in Moralismen und Konservatismus verirrt haben. “Killerspiele” waren das erste was ich persönlich damals als junger Bub mitbekommen hatte.
So, I’m sure you will get better recommendations, because I am actually not very good at researching the details of the artists I listen to, and they might actually not pass some of your requirements, but as you mentioned German might be an option: There’s a very good leftist niche within German rap. One problem I immediately know of about the scene is, that some of them are unfortunately Antideutsche so you get that dogmatic “Israel can’t do anything wrong”-BS, but even with that, there’s some good stuff there that might fit with your requirements. Some songs that I thought of after reading your post that might fit the bill:
Vandalismus - Maskulina
Zugezogen Maskulin - Alle gegen Alle
grim104 - 2. Mai
Danger Dan - Sand in die Augen - As far as I know, he’s part of the Antideutsche movement, at least the group he’s in released a really tone-death, facepalm-worthy, anger-inducing track recently about perceived antisemitism in wake of the Gaza genocide, but this track at least is a nice personal story about the struggle of a father of a daughter in a sexist world
As I said, there will (hopefully) be better recommendations, too, but maybe some of it might be likeable.
