Idk if im right... but i think the tempo in most southern beats is extra slow and they just use the instruments to make it sound fast.... so when your listening it sounds like the snare is hittin on the three everytime because you THINK the beat is fast... listen to it as though the tempo is slow and you can see how they are doin it.... idk dats just what i think... i just started producing...
double time is like when the tempo set at 150 or something high and the snare only happens once a bar at the third beat, so with time doubled hi hats ticking would be at 1/8th instead of 1/16 and so on and so forth
