This script is a total scam. The developer seeks only clicks. The MP3 download from the target page is impossible. The whole thing is really strange, if you choose the MP3 quality, a dialogue comes up, the file is prepared for download and if you click on download you will be redirected to google and don't get a file to download. This is a scam of the highest order. I even turned off the ad blocker, but the same thing as described before happens again. My conclusion, hands off!

If you really want to get this to work, you should put another page in your script. https://ytmp3x.com this website delivers what it promises. All you need is a pop-up blocker to stop annoying redirects.
