Mate you're not gonna convince me that "tracker music" is anything but a vague term. You might have a point in it describing music made wth a tracker, but with Renoise existing these days, that isn't exactly very specific is it? We call these pieces "scene music", or even "keygen music" if you're new to it. It's as useful as saying "DAW music". The music made in the style of old retro games is more specific than just "it was made with a tracker". That is exactly why the term "chiptune" exists; it's music that is made with those old sound chips, or emulations of them. That gets to the heart of the issue.
