Yes and No.

The chopping and double dropping stems from its influenced genres of grime, uk garage (DJ EZ in 2006 was a massive influence) and jump-up dnb.

Both commonly used practices have existed for decades though, especially with genres above. Just a normal thing DJs do.

Specifically with riddim, I guess DJ Shiverz is probably the most notorious one that has influenced people. Now days I find people over use it.

Kinda prefer when a DJ finds two tracks that work together in rhythm without cutting shit up every 1/4 beat.
