No reason for Tech, or any one on Strange to respond to either Q strange or Joker. Especially in the form of a "diss track". They dont deserve an entire diss track between the two of them. Maybe mention them in a couple lines, but beyond that would be giving them too much credit. They both suck and nobody even knows who they are, so whats the point?
Beef is still prevalent in rap, just not between a youtube no name, and one of the best to ever do it. And even if it was, it would need to be based on a legitimate beef, not a couple anonymous ex-groupies who didnt get what they think they "deserve".
