That many downvotes is a bit harsh. Methinks he's referring to the fact that most "music" produced on 8-bit devices in the 1980s had the musical value of an overture for solo kazoo.
"Music which is reminiscent of a game console from the late 80s until the early 90s, where the sound was produced by dedicated 8-bit sound chips, working alongside 8-bit primary CPU and using 8-bit DAC for conversion to analog output."
