It's easy to think that pop music is the most popular genre in the world, especially if you listen to radio a lot, but that's not the case - at least according to Spotify.
It turns out that globally, metal is at least in the top 10 genres and is usually in the top 5. The genre also has the most listener loyalty, with pop a distant second, followed by folk, country and hip-hop.
The genres most popular artists include Metallica, Slayer, Judas Priest, Iron Maiden, Sepultura, Pantera, Cradle of Filth and Anthrax.
Of course, this is no surprise to metal fans, but the major labels should take note. There are some hard core fans there that still buy physical product.
