One website: keepvid.com. You copy the URL from the YouTube video into the "download" box, then click download. A bunch of options should appear, and then you should click "download MP3". That will take you to an MP3 converter website. Click "download", and the song will be on your computer within seconds or minutes (or hours) depending on your internet speed.

See here for the webisite.[].

Also, this better not be illegal. My comp. science teacher showed me this.
