Dude you have like 8 posts, shut the fuck up coward.
Anyways. These songs a melodic and geniunely refreshing to hear because they're fun, they're happy, they're bright and they let you see that he's in a good place in life. He's not trying to please anyone, just express himself and you can tell. His song structure is very original in the fact that it's very traditional. There's multiple dimensions to the composition of his verses. Bridges (which don't exist anymore), melody (which don't exist anymore), extended rhyme word use (which doesn't exist anymore.
All things that were once common and made hip hop sound like music. This song sound wise places it's self in the middle of rap and and rhythm and the theme of his lyrics (I have nothing to prove) is consistent and well articulated if you're willing to listen and think.
He also did something that's rare in hip hop now but was once a foundation. He's in california. His attitude is california, his sound is california. If you close your eyes you visualize california and that's they the videos have direction (relaxation in california with a non californian) the video maker is inclined to show the song because it's vibe is very visual.
MK sounds rejuvenated and inspired. It's really nice, this is the most charisma i've heard him rap with in a while.
