Thank you for the reply.
I tried that too.
Even tried using pin change interrupts, thought maybe it just the delay in reading the digitalRead status for the pins.
Basically, what I wanted to achieve, is that whenever a button is pressed, it will interrupt the currently playing sound clip and play the sound clip associated with the button that was pressed (Even if it was the same button).
I'm using the pinchangeint library.

int resetPin = 2; // The pin number of the reset pin.
int clockPin = 3; // The pin number of the clock pin.
int dataPin = 4; // The pin number of the data pin.
int busyPin = 5; // The pin number of the busy pin.

#define BUTTON02 8
