The Earache Metalizer app from Earache Records has launched on Spotify, bringing the greatest metal music discovery tool to over 20 million users around the world.

Everybody seems to be declaring that heavy music is "back" for 2013 - but true metalheads know that it never went away! Having had both ears to the ground for the past 25 years, Earache Records knows a thing or two about uncovering new music - and now they've created a Spotify app that will help you do exactly that for yourself. The Earache Metalizer is the first-of-its-kind Spotify app dedicated purely to metal music, helping you navigate the myriad metal sub-genres like a pro and allowing fans to create personalised playlists suited specifically to their tastes.

The gritty-looking playlist generator is simple to use; using the sliding bars on the mixing desk to choose whether you want your playlist to emphasise metal, thrash, death or grind - or any mixture of the four - the Earache Metalizer then generates your dream playlist within Spotify. The songs fed into the Metalizer are not restricted to Earache tracks - you'll find everything from Spotify's newest big-name sign-ups, METALLICA, all the way through to PIG DESTROYER, BRING ME THE HORIZON and GUNS N' ROSES; all metal bands, all labels, all around the world. And of course, once you've tweaked and perfected your heavy metal playlist, you can share it with your friends via Facebook and Twitter, before doing it all over again.

This unique and fun tool allows you to create an unlimited number of killer playlists whilst discovering great new music and listening to your favourite bands, all in one place.
