Spotify and Metallica came to an agreement, bringing the metal band’s albums to users of the online music streaming service.

Metallica, once outspokenly in opposition of music file sharing, has just allowed their full catalog to be accessed through Spotify’s database. Every single one of the band’s albums

Drummer Lars Ulrich appeared on stage with Mr Parker, a Spotify investor, to discuss their bitter legal battle that took place in 2000.

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.

So why did Metallica finally license Spotify? It's actually quite simple: they're getting paid, on terms they control, through a label they created and control. Which means, no more intermediary, no corporation squirreling money into recoupment accounts and revolving financial buckets. This is reliable cash for Metallica, not a tiring audit.

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

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.

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.

Could a single bro-hug symbolize healing for the music industry after a decade of digital strife?
