Remember the first rap song you heard? Some of your favorite rappers and DJs certainly do. While hip-hop celebrates 50 years of life, The Associated Press asked some of the genre’s most popular artists to recall their first memory of hearing rap and how the moment resonated with them.

In interviews with more than two dozen hip-hop legends, Queen Latifah Chuck D, Method Man, E-40 and eight others cited The Sugarhill Gang’s “Rapper’s Delight” as the first rap song they heard. But not all were hooked on the new musical style by that track, and their answers reveal the sense of discovery that marked rap’s early years.

Hip-hops roots are traced to 1973 in the Bronx and it took a few years before rap records emerged — “Rapper’s Delight” was a major catalyst for introducing the rap music to a much broader audience.

Here are the stories of a dozen hip-hop stars who got hooked on the genre around the time “Rapper’s Delight” ruled. In part two, another group of legends and young stars reminisce about connecting with rap by hearing songs by acts like Tupac Shakur, Grandmaster Flash, 2 Live Crew or Run-D.M.C.
