If you could only use one magic button, which would it be?

You get a visit from the Break-dancing Faerie and her Magical Boombox. Instead of three wishes you get to choose one magic button to use—indefinitely. Meaning you can keep using the button that you choose.

Your choices:
PLAY. Live life as is.
REWIND. Go back in time. Changes future unless you do everything exactly the same.
FORWARD. Skip the painful (and boring) parts.
PAUSE (and UNPAUSE). Take a moment to smell the roses (or take a nap). The rest of the world is on PAUSE. Does not affect the future. No robbing banks.
RECORD. Can relive any moment—as it already exists. No changes to how it already played out. Break-dancing Faerie is old school though. You only get one cassette tape—60 minutes of recording time.
