Is it illegal to convert YouTube videos into mp3 for iTunes?
I don't think it's illegal, since YouTube does offer the opportunity to convert a video to an MP3. There is an online program that makes the conversion easier and enables a person save the flv files as mp3. You can go to, http://www.ehow.com/how_5066066_download-youtube-songs-onto-itunes.html, to get details of how you can do that.
Certain sites, yes i found justconvert.it great site
The sound quality will be bad. Worse then radio
I think if we don't used for business, it is legal.And to convert youtube to mp3 in itunes, you can just use a free program(http://www.leawo.com/youtube-downloader/) or use a complete video software to enjoy more effects.Maybe you are interested in the Easter deal(http://www.leawo.com/promotion/easter/).
