I've got an Adafruit VS1053 shield hooked up with a button. I want to play ambient star trek noises and then a blast off countdown when a button is pushed. I'm using and if / else and it's not working. Code below.
Currently, the ambient sounds play and then the push button doesn't change anything when pressed. If I take out all of the content within the else brackets. The button works as expected.
This is for a "spaceship toy" for my kiddos, an image is attached. I want the ambient sounds on when that push button isn't pushed. The audio is controlled with a separate Arduino that shares that push button.
Any thoughts?

@Mark T I do have an external pull-up.
To elaborate more, The pushbutton works when I take out the ambient sound code. When the else argument is blank the push button plays the other track as expected. When I add in the else content and the push button gets pressed the ambient sound just keeps playing and nothing happens.
@halloweenrick, not error messages. Grounds are tied together.
So then that makes me think its a programming issue - in that there is no "cue" for the ELSE command to activate. It reads that IF happens when a button push occurs HIGH, but nothing to activate when ELSE occurs- no button push, no actual timing of the mp3 length, etc. I think you need to look at State Machine language here, in that:
Case 1: Button HIGH- activates MP3 player
Case 2: Button LOW or length of time (delay or millis timing of mp3 length)
Try adding a DELAY of the MP3 Length of the Blast off sounds, I'm sure it can't be very long as a quick and dirty solution to see if that helps any in State Machine/Case code.
Here is my current code. The ambient sounds called the startrek.mp3 track play, but when I hit the pushbutton nothing happens. It keeps playing the startrek sound and does not play track003.mp3.

Oh hey! This shield has Interrupt- which is very similiar to the DF Mini Player's Advertise command- which will allow you to play another MP3 file on a button push, and the music will resume where it left off! Its right here in the code you posted:
// If DREQ is on an interrupt pin (on uno, #2 or #3) we can do background[color=#222222][/color]
// audio playing[color=#222222][/color]
musicPlayer.useInterrupt(VS1053_FILEPLAYER_PIN_INT); // DREQ int[color=#222222][/color]
musicPlayer.GPIO_pinMode(2, INPUT);[color=#222222][/color]
pinMode(button, INPUT);
See if you can move your Pushbutton to Pin 2 or 3 and see if your library has an Interrupt example you can follow. That should solve everything.
What happens in the serial monitor when you just print inside the if/else?
How long do you hold the button? Does holding it down for a long time make it work?
Remove the delay in the ambient section. Leave it in the takeoff.
If print works put the play first and see what happens.
