no,
1. open the link
2. you will see a search bar, type the songs name or copy the link of the song you want from youtube
3. you will choose the type you want the file to be in (mp4/mp3)(i recommend 144p if you want a fast download)
4. convert
5. its ready, but move it from the file it saved in it might delete by itself when you close chrome or what you used (it might only be just for me but whatever)
