Oh srry it's kind of hard to explain how
I'll try to
First you copy the yt link
Then you search on google youtube convert to mp3 (I think)
I click any website and if it seems safe I use it
I paste the link in the place u should paste in it
U click download mp3 and done
(BTW sometimes when u click the download button or anything in the website it sends you to a random website, click back as fast as possible then try to download again)
