Happy Holidaze! This amazing holiday music set is performed entirely on smartphones and tablets by the North Point Ministries and presented online for your holiday listening pleasure. They got a lot of requests from folks wanting to know which app allowed them to play which instrument, so they assembled a list that will lead you right to them. As with other entries under Singularity Music, I had to immediately start tracking down and installing a few of these, in the hopes I could learn how to make more than random noise out of them.
