Fix CORS error playing mp3 files from another website

Question

The problem I'm having is that my React app cannot play audio from other sources and gets a CORS error. Example: https://audio.podigee-cdn.net/1041740-m-0fcf92e897e7cd93200a43cf103a75fb.mp3

The strange thing is that when I visit https://www.w3schools.com/tags/tag_audio.asp, I enter the above URL and click play.

On my local React app I then get a 302 status and a redirect. The audio tag contains crossOrigin="anonymous" and the url in the src element.

On W3Schools, it redirects somehow and I only get status 206 from the redirected URL.

How to reproduce:

1. git clone https://github.com/SamTV12345/PodFetch.git
2. Follow the README instructions in the "Build" section
3. git checkout origin/development
4. Add any podcast with more than 5 episodes.
5. Click CloudIcon

You need to import the mp3 URL via new Audio(url) instead of XMLHttpRequest to avoid CORS. For example:

class PlaySound extends React.Component {
  constructor(props) {
    super(props);

    this.state = {
      play: false
    };

    this.url = "https://audio.podigee-cdn.net/1041740-m-0fcf92e897e7cd93200a43cf103a75fb.mp3";
    this.audio = new Audio(this.url);
    this.togglePlay = this.togglePlay.bind(this);
  }

  togglePlay() {
    const wasPlaying = this.state.play;
    this.setState({
      play: !wasPlaying
    });

    if (wasPlaying) {
      this.audio.pause();
    } else {
      this.audio.play();
      setInterval(()=>{
        console.clear();
        let seconds = new Date().getSeconds();
        let points = '.'.repeat(seconds % 4);
        console.log(`Loading audio${points}`);
      }, 1000);
    }
  }

  render() {
    return (
      

         {this.state.play ? "Pause" : "Play"}
          
        
      
    );
  }
}

ReactDOM.render(, document.getElementById("root"));
