In my early 30s here.
Last rappers that really impressed me like that:
Lupe,
Kendrick,
Childish Gambino
Joey Badass
Jay Electron.
I still listen to hip-hop and always will as it's my favorite musical genre, although I listen to a lot more other styles nowadays. My criteria for lyricism isn't the same as the past. If it sounds good then i'll rock with it, but those times of strong lyrical swordplay probably aint ever coming back. Gotta deal with it
