That worked! Played no problem. I tried to make the same edits to the pit droid sketch...but it's doesn't seem to work. I am probably missing something. I posted the original sketch for the Nano below and the edits I made to it underneath that. All I did was remove the SoftwareSerial.h and changed SoftwareSerial to Serial1. Thanks again for your help, I spent days racking over this...lol.
// This sketch was created by Dan Massey July 4_2021. It controls an Adafruit NeoPixel and
//a DF Player Mini to animate a Pit Droid. It also has a switch that can control the activity level of the sounds.

#define PIN 7 //this is the pin on the Arduino that goes to the input of the first NeoPixel.
// Parameter 1 = number of pixels in strip
// Parameter 2 = Arduino pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
// NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
// NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
// NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products)
// NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
// NEO_RGBW Pixels are wired for RGBW bitstream (NeoPixel RGBW products)
Adafruit_NeoPixel strip = Adafruit_NeoPixel(12, 7, NEO_GRB + NEO_KHZ800); //the settings for the type of NeoPixel you are using (see 8 of the lines above).
// IMPORTANT: To reduce NeoPixel burnout risk, add 1000 uF capacitor across
// pixel power leads, add 300 - 500 Ohm resistor on first pixel's data input // these are things to remember to do if you are connecting to an actual Neopixel set.
