He doesn't do the autotune vocal psychedelia thing is probably why. Not a particularly good vocalist but he's got some fun songs, more danceable than a lot of stuff around atm, but that trap influence is still there in the beat.
This was a big one from last year in a similar vein:
In general though, I think the trap influences are becoming more truly integrated into dancehall rhythms than before, as opposed to just being bolted together or layed on top of each other, if that makes sense. More of a true synthesis.
Hard to describe how though.
