“exampletext.mp3” doesn't at all match with “SHMC.mp3” I guess its just an example to show how you wrote and I hope you took care of this following things: 1) The background music is in “sounds” folder only 2) The name and extension should be exactly the same in folder 3) uppercase and lowercase should also be the same

What have you done? Their is tons of thing what I said. So to which one are you referring?

First off, that line does not deal with file "SHMC.mp3", which the error message refers to. Secondly, there is no context given as to where the line is within the class. If you give the proper line of code, also include a description of where it is in the class or, better yet, supply the entire class code.

First, @Roshan123, I meant all three thing in the list. Second, @danpost, I know that "exampletext" and "SHMC" are different, thank you. I wanted to edit the first post after posting the error code but couldn't. And Third, Dan, it was in MyWorld, in the main block of code, under I also tried above the yellow box. What did I do wrong?

As in

*there

what do you mean by the "full script"?

Just to be sure, since the computer is very strict about typos: You wrote "sound" (without s at the end). But the folder in your project is called "sounds" with an "s" at the end, right?

I mean code of every class which is dealing with the music

yes
