Make a versus mode game. Set the song to Sugod or Kan Kan. Make sure you have opponents. Set the speed to x8 and the difficulty to hard. Then, press all the game buttons (S D F [Space] J K L) until the song ends. Your opponents cannot win because it is difficult. They will quit. Continue playing the game until you win. Keep on doing this repeatedly until you level up. Note: Make sure your opponents quit easily.
