Can I use Mp3 Player kit as doorbell?

Is it possible to use this kit as a doorbell ?
Specifically, would I wire the doorbell directly to the random button ? or the play button ? What happens if someone pushes the button twice ? Is it possible to adjust the key debounce on the play button so two pushes would not result in a play/pause scenario ?

Thank you

I think you can wire the doorbell button to one of the preset buttons.
Put one MP3 file in the folder related to this button.
When the doorbell button is pressed the piece of music is played once.
If the button is pressed again while playing, the player restarts the piece.
