Number 1 Hip Hop song of all time?

One of the most widely recognized and highly regarded Hip Hop songs of all time is "Rapper's Delight" by The Sugarhill Gang.

"Rapper's Delight" was released in 1979 and is often credited as the first commercially successful Hip Hop song. The track features a catchy beat, fun lyrics, and a memorable flow from the trio of MCs. It also helped to popularize Hip Hop music outside of the Bronx, where it originated, and introduced the world to a new sound and culture that would go on to shape music and popular culture for decades to come.
