I listen to probably a majority of communist songs though I really like Lyubeh (related to the soviet union but not communist), IU, Gfriend, TWICE, (don’t fucking judge me) miscellaneous klezmer bands, recently teresa teng, as well as various video game osts. (persona 4. yokai watch, etc.)
Electric Light Orchestra, Red Hot Chili Peppers, Pink Floyd, The Decemberists, The New Pornographers, The Avett Brothers (their older stuff), Tally Hall, Ghost, and Korn. A bit of everything
I saw ELO live in 2019 and it was pretty great.
ELO? DaiconIV will never die!
