Pick a mix that you're very comfortable with and can run up long note streaks, since you need a good 50 in a row to earn a rewind. Once you earn a rewind, use it in an area with few notes, and preferably no recent fader moves. Spin the platter 360 degrees and hit all the notes while the multiplier is doubled.
Once you do this four times (they don't need to be all in a row), you will earn the Achievement. This can be done on any difficulty.
Remember, if you activate Euphoria before you do a rewind, you won't have to worry so much about the fader position when it's done rewinding because Euphoria will handle the fader moves for you automatically.
