Don't know what this code does

// play file 004.mp3 in folder advert02 -- switching sound
    Serial.write(0x7E);
    Serial.write(0x07); 
    Serial.write(0xA0);
    Serial.write(0x30);
    Serial.write(0x32);
    Serial.write(0x30);
    Serial.write(0x30);
    Serial.write(0x34);
    Serial.write(0x7E);

but I feel it should be put in its own function, lets say playMp3File();

This function should be called from shortKeyPress(). Have you read the comments in my code ?
