FSR audio

this one boggles me a bit; I am trying to play an audio track with the press of an FSR and a second track when a second FSR is pressed. Wired as per adafruit fsr/micro page on their site with relevant corrections. If I test player/sd card etc by putting ‘musicPlayer.playFullFile(“track001.mp3”);’ in setup it plays fine but can’t seem to trigger ‘musicPlayer.startPlayingFile(“track001.mp3”);’ in loop.

#include <SD.h>
#include <SPI.h>
#include <Adafruit_VS1053.h>
#define BREAKOUT_CS 10 // VS1053 chip select pin (output)
#define BREAKOUT_RESET 9 // VS1053 reset pin (output)
#define BREAKOUT_DCS 8 // VS1053 Data/command select pin (output)
#define CARDCS 4 // Card chip select pin
#define DREQ 3 // VS1053 Data request, ideally an Interrupt pin
int fsrPin = A0; // NOTE HOW A0 IS REF TO AS '0, FSR and 10K pulldown are connected to a0
int fsrReading; // analog reading from FSR resistor divider
Adafruit_VS1053_FilePlayer musicPlayer = Adafruit_VS1053_FilePlayer(BREAKOUT_RESET, BREAKOUT_CS, BREAKOUT_DCS, DREQ, CARDCS);

void setup() {
SD.begin(CARDCS); // initialise SD card
musicPlayer.setVolume(20, 100);
musicPlayer.useInterrupt(VS1053_FILEPLAYER_PIN_INT); // DREQ int

void loop() {
fsrReading = analogRead(fsrPin);
if (fsrReading < 1000) {
musicPlayer.startPlayingFile(“track001.mp3”); /musicPlayer.playFullFile(“track001.mp3”);/
else {

Try printing fsrReading. What values do you see ? How is the sensor wired ?
