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.)
Pretty much anything that doesn’t have obscenely terrible lyrics (unless it’s in a language I don’t understand), or blatant pro-capitalist shite; I prefer fast-paced music so I typically increase the tempo. As you mentioned, many video games have really good soundtracks.
