It’s already been all over the internet. But now, after the initial hype, it’s always worth to bounce content like this.
The One Lap Top Per Child Project, has joined forces with an array of audio artists, and gathered a huge collection of high quality content. While it’s confusing because of it’s size and categorization, it’s still worth searching all the way through.
Since the project has received an enormous amount of traffic due to popularity, the files have been moved (or in the process) to p2p. So you’ll need a bittorrent client in order to access these.
