Few days ago the popular content download software "youtube-dl" was taken down by RIAA. They left a notice in the GitHub-Repository that youtube-dl violates copyrights. In my opinion this is a shame. With youtube-dl it was possible to download any content from youtube. That means you were also able to legally download content that was not protected by any content license.
Grooveshark was a great Social-Media-Service for connecting people through their love for music. I enjoyed it so much to meet people from all over the world who also love the same music as I do. Many independent musicians were able to advertise their talents there. It's a pity that they had to shutdown this awesome service.
