The easiest way to get this is to make sure you select the right turntable. You unlock the "powered" turntables through normal gameplay, so the trick is to pick the right one. On this particular set, I used the platter tapper one, which gave me more points for each platter button I hit. If you're not so good at the taps, then you can probably do it with the scratch master deck.
Of course, this implies you have some skill. Unfortunately, the special decks can't do everything, but if you're pretty close to getting it, they sure do help.
