[music] Of Course You Hear What I Hear — Christmas Music Season Is Totally Data-Driven … How music-streaming services and Radio work out what songs to play at Christmas and when to start. ‘Any half-decent band will cut a quick holiday track every now and again. It was McDonald’s job to develop an algorithm to find that song and make sure nobody hears it on Spotify radio for most of the year. “We actually have a fairly intricate mechanism to try to identify Christmas music,” McDonald said. First, he builds a list of obvious holiday songs. He then identifies the albums those songs appear on. Then his algorithm looks at all the other songs on those albums to see how often they appear elsewhere, and will try to decide if they’re Christmas songs by iterating the process to figure out which songs only appear on other Christmas albums. The process isn’t infallible, but after enough repetitions, McDonald said, “we have a pretty good idea of a fairly complete universe of Christmas songs.”’
