Love the way they use a Bruno Mars sample but cut it up to make it sound like something Tupac would have rapped on. I understand your argument and don't necessarily disagree with it entirely but this was poor choice of instrumental to pick if you're arguing that hip-hop is very different to how it used to be during 2pac's time.
On that topic, I wonder what people thought when they heard things like California Love or Sky's The Limit for the first time. I bet they thought it was very different and had changed from the music of Marley Marl, Sugarhill Gang, Kurtis Blow etc.
Hip hop isnt one specific sound, its a whole culture (as shown by the pillars of hip hop). I do understand what you're saying when you say it's changed from what it was but I wouldn't agree that its diminished, just perhaps the better artists are now more underground (excluding a couple e.g Kendrick)
