Metallica at Outside Lands is Number 1!

Will they?! Won't they?! Metallica drummer Lars Ulrich bursts onto the new cover of Metal Hammer to talk about Metallica's plans for 2013, that immense 3D movie, and whether we'll actually get that new album next year or not.

Metal gods Metallica have ended their lockout of the streaming music service, adding classic albums like Master of Puppets, Ride the Lightning, and yes, …Justice for All to the site.

At a press event in New York, Daniel Ek, the founder and CEO Spotify, unveiled tools to help users of the popular global music streaming service discover new music. And he announced a coup for the service: Spotify struck a deal with longtime online music holdout Metallica to make all of the band's music available for streaming.

The members of Metallica are arguably the world's most renowned opponents of online music sharing...

Lars Ulrich, Metallica drummer and famed commando in Internet music wars, was also on hand to announce that Metallica's entire catalog would finally be available on Spotify

Metallica, a band that for years fought to keep its music off peer-to-peer sites, has agreed to allow their entire decades-spanning catalog to be freely available on Spotify.

The company made the announcements at a splashy New York event on Thursday that included a conversation between Spotify backer Sean Parker and Metallica drummer Lars Ulrich.

The band’s battle with Napster more than a decade ago was legendary, and ironically enough, at today’s announcement event in New York, Metallica drummer Lars Ulrich appeared with Napster co-founder Sean Parker, who now serves on Spotify’s board. It looks like the two one-time adversaries (pictured above at the press conference) have buried the hatchet.

Metallica had previously declined to stream its music. Fans can now access 30 years of the Rock and Roll Hall of Fame band's recordings.
