We love #SongAssociation, but we really love it when groups stop by to play. On today's episode, Christopher, Erick, Joel, Richard, and Zabdiel — collectively known as #CNCO — give it a go. Tune in as they sing some of their own hits like "Reggaetón Lento (Bailemos)" and "Hey DJ," and give a nod to iconic bands like the Jackson 5 and The Backstreet Boys.
