The /mu/ meme stems from the music-themed imageboard on 4chan, notorious for its elitist culture and obsession with 'essential' album charts. It is best known for popularizing indie and experimental acts like Neutral Milk Hotel, Death Grips, and My Bloody Valentine, often turning their album covers into recurring visual motifs. The meme usage typically revolves around the distinction between 'plebeian' (mainstream) and 'patrician' (underground or high-art) musical tastes. Whether it’s sharing a 'topster' grid or mocking someone’s 'entry-level' discovery, /mu/ culture represents the ultimate gatekeeping-meets-appreciation hub for internet music nerds.
