Rap Life is home to hip-hop's heavy hitters and its vanguard—the songs that speak to the moment and define the culture today. This week that would be Kendrick Lamar’s runaway freight train of a diss track “Not Like Us.” Lamar’s Godzilla vs. King Kong-like back-and-forth with Drake was moving so fast and furious that it was hard to keep up with who released what song and when for a minute, but “Not Like Us” endures. Blame it on the Mustard (formerly DJ Mustard) Young California-leaning beat or, most likely, the absolute barrage of quotable catchphrases, but “Not Like Us” is not likely to go away anytime soon. Listen to the song on Rap Life now, and if you hear something you like, add it to your library.
