I always thought Shazam / Soundhound just made money from displaying ads or directing users to purchase music, but as it turns out, the far more lucrative side is an incredibly accurate ratings and attention meter for producers. The modern Nielson box, with geolocation and profiling, but for music.
By studying 20 million searches every day, Shazam can identify which songs are catching on, and where, before just about anybody else. “Sometimes we can see when a song is going to break out months before most people have even heard of it,” Jason Titus, Shazam’s former chief technologist, told me. (Titus is now a senior director at Google.) Last year, Shazam released an interactive map overlaid with its search data, allowing users to zoom in on cities around the world and look up the most Shazam’d songs in São Paulo, Mumbai, or New York. The map amounts to a real-time seismograph of the world’s most popular new music, helping scouts discover unsigned artists just as they’re starting to set off tremors.
