I was just wondering if there was a way i could ask a user for a .mp3 link or somthing similar to their favorite song and have it play... ive been getting a error were it will read the URL i try to answer and say // in the url is 'Invalid use of operator.' Thanks!

This is what I have

song = input('Enter link to you favorite song : ');
fullname = 'song';     %change as required
try
    [y, Fs] = audioread(fullname);
    PO=audioplayer(y,Fs);
    % Play audio
    playblocking(PO)
catch ME
    uiwait(msgbox('Could not open that file with audioread'));
end

I'm not sure if this as a typo or not, but song shouldn't be in quotes. It would help to use code formatting tools to format your code.

It would also help if you gave a specific example of the input the user provided that wasn't working. Perhaps if you tried this:

song = input('Enter link to you favorite song : ');
disp(song) % What output does this line provide? A specific example would help others help you.
fullname = song; % song should not be in quotes on this line.
try
   [y, Fs] = audioread(fullname);
   PO=audioplayer(y,Fs);
   % Play audio
   playblocking(PO)
catch ME
  uiwait(msgbox('Could not open that file with audioread'));
end

What does the display look like?

So it still gives me the error on the input which is Invalid use of operator on https://downloads.khinsider.com/game-soundtracks/album/speed-racer-original-game-rip/02%2520Speed%2520Racer%2520Theme.mp3 or any thing that end with .mp3
