Metallica drummer Lars Ulrich and Napster cofounder Sean Parker met for an interesting conversation at the Spotify press event in New York City on Thursday. Spotify CEO Daniel Ek's announcement that Metallica would be joining the music streaming service was followed by an interview with Parker, who is a Spotify board member, and the outspoken Ulrich. The two talked about their legal feud and long history. You can watch the entire Spotify event below, or skip to the Parker/Ulrich Q&A at the 36:00 mark.

Spotify also announced a few new features including a Follow tab which allows users to get music recommendations from friends, artists, influencers and media in real time. The all-new Discover tab uses social tools with content from Pitchfork, Songkick Tunigo and more to continually seek out the most relevant content for you.

The page includes:

· New single and album releases from the artists you follow

· All the music and playlists shared by influencers you follow

· Intelligent recommendations based on your listening history including music, reviews, and concerts

Spotify has announced that free radio play is coming to the U.S. in a few days. The update was supposed to roll out starting today, but Spotify decided it wasn't quite ready for public consumption. iPhone and iPad users will have access to an unlimited amount of music once the new radio feature is integrated into the iOS app.

The update offers limitless streaming radio stations and the ability to like your favorite songs so you can easily find them later. Free users will have to deal with advertisements, while Premium users will continue to enjoy an ad-free experience. Spotify is available to download for free in the App Store. It's compatible with the iPhone, iPod touch and iPad, and requires iOS 5.0 or later. A Spotify Premium account is $9.99. Read on for a complete list of upcoming changes.
