If you've ever heard of Napster or seen The Social Network, then you probably know the name Sean Parker.
According to Forbes and All Things Digital, the newly minted billionaire has joined a group of investors looking to buy Warner Music Group, one of the major mainstream labels that sued Napster for copyright violation and had a hand in shutting the site down.
Parker, who debuted on the Forbes Billionaires List last week thanks to his 3% stake in Facebook, has been working as a consultant for European music streaming site Spotify, trying to get the service off the ground in the U.S. This has led to rumors that he's only interested in buying Warner Music to get Spotify a license to stream its back catalog.
