There will be people who won't appreciate what this week means. Hell, I'd put money on the fact that there are plenty of people who have no idea who Kendrick Lamar even is - which yeah, if you've been listening to hip-hop at all in the past decade that'll blow your mind, but a mainstream crossover at this level does mean a lot more. Yeah, there have been plenty of acts who have scored a fluke #1 hit, even within hip-hop - but when was the last time an MC with actual bars snagged the top spot? Here's a little perspective: Biggie got there, but Tupac didn't. Neither did Nas. Jay-Z needed Alicia Keys to get to #1 in 2009. Eminem and Kanye both got there a few times, but they are both pop culture phenomenons in their own right. Lil Wayne never got there on his own - nor has Nicki Minaj or Drake. With Kendrick getting the solo #1... that sort of hit can create a sea change in pop culture, especially if it has any longevity.
