Interrupt simple Audio player

Maybe someone can help.

I have 2 files that i want to play using the simple audio player and due board.
Depending which pin i pull high as different clip is played. The problem that i have is that i cant seem to get the interrupt of one clip by another working.

I am trying to do it with a if loop and a break but it does not seem to work.

void loop()
{
int count=0;

// open wave file from sdcard
File myFile = SD.open(“test.wav”);
if (!myFile) {
// if the file didn’t open, print an error and stop
Serial.println(“error opening test.wav”);
while (true);
}

const int S=1024; // Number of samples to read in block
short buffer~~;~~
~~ Serial.print(“Playing”);~~
~~ // until the file is not finished~~
~~ while (myFile.available()) {~~
~~ // read from the file into buffer~~
~~ myFile.read(buffer, sizeof(buffer));~~

~~ If (digitalRead (button1) ==HIGH)~~
~~ {~~
~~ break;~~
~~ }~~
~~ // Prepare samples~~
~~ int volume = 1023;~~
~~ Audio.prepare(buffer, S, volume);~~
~~ // Feed samples to audio~~
~~ Audio.write(buffer, S);~~
~~ // Every 100 block print a ‘.’~~
~~ count++;~~
~~ if (count == 100) {~~
~~ Serial.print(".");~~
~~ count = 0;~~
~~ }~~

So what I am actually asking is how to stop 1 file and play another?
