Further to my comments in the following article:- http://www.4barsrest.com/news/detail.asp?id=18080#.UuEUis9FCUk I would like to explain my views on the matter a little further. It is specifically mentioned in Soundcloud's terms and conditions:- https://soundcloud.com/pages/copyright that posting copyright material on the site without permission is illegal. I'm sure many users are not aware of this condition, so feel it needs to be pointed out. (I haven't yet found an equivalent proviso on YouTube, but hope it exists) Why is it illegal? Firstly, it is not permissible to record performances at concerts or contests unless a facility fee or licence has been paid to the organisers or venue. This is how World of Brass, for example, produce official recordings. Secondly posting a recording on Soundcloud, as mentioned, is illegal unless you own the copyright in the piece and the recording, or get permission form whoever does. It is not a particular concern that such uploads are directly depriving composers of income, but it does worry me that such 'broadcasting' means that many players and conductors are now using YouTube and Soundcloud as points of reference; this has had a direct and significant impact on CD sales. Many such posted performances are poorly recorded (and sometimes poorly performed) and can therefore constitute an inadequate representation of the work. Composers do in fact have 'paternal rights' which allow them to prevent the broadcast or recording of performances they feel do not present the piece in the best light. Never used this myself, but been tempted....! I don't have a cure for this disease, as the digital genie is already out of the bottle, but it does appear that PRS are prepared to act on behalf of its members, should an infringement be notified to them. Think on!
