I am new to mixing/DJing and have hit a snag. I have a s2/traktor and am pretty familiar with how they work, but i dont know where to go from here. All the tech stuff aside, i am not sure how to practice mixing. What do you do to just practice techniques or even know what song you want to play with next...? Just feeling a bit overwhelmed by it all i suppose...
