SoundCloud, the Berlin-based audio streaming site, is getting worried about copyright violations on its site. SoundCloud is like YouTube for audio; it allows anybody to upload any kind of audio. This naturally opens the door to people uploading copyrighted audio. Just as YouTube has had to do, SoundCloud now wants to work out agreements with copyright holders over what to do when this happens. A Bloomberg report today says SoundCloud, which has 250 million users per month, has been talking to Universal Music Group, Sony Music Entertainment, and Warner Music Group to get licenses so it can legitimately stream songs owned by the labels. Bloomberg says people close to the situation report that SoundCloud has offered the labels equity in the company in exchange for a promise that they won’t sue for copyright infringement. SoundCloud is offering each of the label groups a three to five percent stake, the people said.
