Turns out Utada Hikaru has been known to be both. She has played the game everyday since she was five years old! Then a couple years ago she played in a broadcasted Tetris tournament against thirty contest winners. Out of the thirty players, she was only defeated by four. Three out of the four players were among the first to go up against her. After what seemed like a warm up, she became unbeatable. She later posted her 99,999,999 score and stated:

You need perservance or obstance to make it this far. (lol) A woman’s obstance! Hahahahaha!

Supposedly she joined the Nintendo Tetris Team and the only player now to ever beat her is on the team with her. However, there’s been no recent news of her Tetris career.

Utada Hikaru came out with her latest album in March, Heart Station. Since then she has been promoting the album.
