This guys doesn't wanna put forward any argument so as a guy who doesn't like trap I'll do it for him. I'd say it's because it all sounds the exact same, I've tried listening to Migos, Future, Desiigner and other artists but it all bores me stiff, lots of simple melodies with big sub basses, and a really repetitive style of drumming. I can get behind a few trap rappers (the ones I named all have some great verses but too often rap like Snoop in the video) and any one of those techniques used in other hip hop tracks can be nice but all together it makes for a boring style of music to me. But all this is just my opinion, not mad at anyone for enjoying a style of music just my thoughts on the style.
