How to know if the audio playing has reached its end or stopped?

How to know and how to stop the copier or copy() when the audio playing has reached its end or stopped?

Just read the Wiki: The most important basics!
or the class documentation

Can you give me a shortcut to more detailed documentation of what I mean?

here is my code:

while (Serial.available() > 0) {
String inputString = Serial.readStringUntil('\n');
url.begin(inputString.c_str());
for(int x; x > 0; x++){
copier.copy();
}
}

i use "for" looping to run the copier, but I don't know how many iterations it takes, is there a solution to my problem?

You still did not read the Wiki! You can find the answer there in the last sentence of the Copy Section!
I spent quite some time to put together the documentation to avoid these kind of unnecessary questions
