Never worried about it too much but in aesthetic and construction its actually one of the grimier songs on the album. Sounds like demo or mixtape quality. Its just a basic loop, as far as I can tell theres nothing added. The EPMD song is a much more produced higher quality mix. Classic song though, never understood why some hated on it.
A lot of 90s records were mixed funny. A lot of over bassy, muddy mixes with vocals low in the mix. Sometimes it works, other times its a weird choice because theres nothing going on in the high frequencies except rapping. There are certain songs that sound like you're listening to them through a wall or something. Still the greatest music era. That was more the hardcore sound of the early 90s, by the end of the 90s, the music sounded very slick and shiny.
