I know what you mean and what's wrong with the 'bubble sound'? Oh and it's actually a percussion sound.
I could give it more power but it isn't really meant to have power. I created the drop with the intention of it being something you can relax to (not saying you can't relax to chill drops with huge power because you can). I will see what I can do I suppose. Also, how do you suppose I give it more power? Add sound effects maybe, vocals, more bass, switch up the drums?
