This isn't "racial bias" and has nothing do with race, but the types of music MP3 developers, who were western men, decided to use as a reference. Famously, Karlheinz Brandenburg focused on making 'Tom's Diner' sound good, which suggests the mp3 model is strongly optimized to rock music and, as others have claimed, sounds sub-optimal when encoding non-Western music.
Your comment was good until you got into an unfounded and reactionary "reverse racism" accusation.
