Where can I get a simple YouTube to MP3 site for a social music night?

<span style="font-size: 10pt; font-family: Arial;" data-sheets-root="1">My friend was over this afternoon, sharing YouTube playlists. Needed a free way to save them as MP3s. Found YouTube converter free, a smooth conversion site. It offers quick, high-quality downloads, supports playlists, and requires no software or signup. Just paste links for fast results. It made our music session so much more enjoyable.</span>
