NEW YORK (AP) – Metallica is finally getting into the “stream” of things. The band says it is going to let its music be streamed online – bringing 30 years of their recordings to Spotify. How big of a deal is this? A dozen years ago, Metallica was among several acts who sued Napster – a site on which users “shared” copyrighted music. The suit forced Napster to go legit and that laid the groundwork for what are known today as streaming services. Metallica drummer Lars Ulrich says the group sat back for a while to see how the streaming industry would go – and is “beyond psyched” to work with Spotify.
