Remember Napster? Seven years ago, an 18-year-old smart college student revolutionized file sharing and the music industry by releasing Napster. In just a few days, thousands of people had already started to download music with Napster's help. Over less than a year, it gathered 60 million users to share music through the site.

But of course, when good news spread too much, problems show up. So it happened to Napster. With such a huge popularity, it couldn't avoid coming into the music industry's attention. So on December 7th 1999, the Recording Industry Association of America filed Napster for copyright infringement. This was only the beginning of Napster's end.

Metallica were the ones to contribute a lot to the file against Napster. But at the beginning, the site managed to win the trial. It was only in 2001 that it had to shut down to fulfill the court's request.

A period of paying fabulous amounts of money followed - songwriters, music publishers, record labels, they all had to be rewarded for being "robbed" by Napster. So it had to pay everybody around 50$ million.

But here they are again! They launched back today a free, advertising-supported version of its music platform. Users can listen to more than two million tracks for free. The site is updated every Tuesday with the latest releases.

What's Napster's secret this time? As far as it seems, music can only be listened to online, it cannot be downloaded.
