“Mistletoe” – Justin Bieber
Adam: We spent the summer of 2011 making Christmas songs.
Nasri: [Laughs] Yeah, Scooter called me saying they were making a Christmas album and the next day “Mistletoe” was done. We just have this chemistry with Justin. He has a really good artistic vision of himself. That song and that album was really easy for us and fun, but it was challenge, because we were able to come up with what we have now which is the new Christmas album standard.
