Contacting Artist

So after considering copyright, the status of the artist and the type of music they perform; we have decided to go with UK Pop/RnB singer Angel. To contact him we have used twitter since it's the easiest way of contacting this up and coming artist. We sent him a message explaining who we are and why we wanted his permission; he said it was fine for us to use any of his songs in his mixtape so we browsed through it a few times and found the perfect song. So we then contacted him again to receive the lyrics.
