How do I record music off of YouTube on an iPhone?

Get an recorder app, and put the phone close to the speaker, and play the song, it should automatically go to your camera roll.

This is only possible on galaxy note 2. Not on ios, android 4.0 below, wp8 below. N2 has a downloadable 3rd party app for this.

When you use YouTube you agree to their Terms of Service which state that you will only access the media on the site and not download or record it otherwise.
