I like listening to Hip-Hop songs, and then finding the songs that their beat samples came from, and then listening to them as well.
for example:
<------ Nas, "Hip-Hop is Dead"
came from
<----Incredible Bongo Band, "In-A-Gadda-Da-Vida"
<--- Incredible Bongo Band, "Apache"
In-A-Gadda-Da-Vida is particularly amazing, the entire damn song is crazy. someone in the youtube comments said "If I were a superhero, this would be my theme song". and I agree completely with that sentiment.
