You need volume for this. Click the green flag. @wolfypaws996, The instructions will tell you how to add music. If youtube doesn't allow you to access it then go to youtube then type the music that you want to paste and then highlight the URL so you can copy it. Then, search up "Youtube Converter mp3" to convert. In the middle you will find a little bar to paste your link so paste and there is also a little button which converts to mp3 or mp4 depending on your device so toggle that if necessary. Wait for a little while for it to convert. It should show up in your files after it's done converting so go in scratch, make a project, go in "Sound", upload sound, and there you have it.
