I just got a notification about one of my tracks from the SC page linked at the end of this post. My concern is that they will do what they seem to be doing with many other people's work - find a way to post it at their page and turn everything into a free downloads. As with all of us here with original work it is -- our -- prerogative to make tracks free to download or not.
In short, this looks like blatant copyright infringement and essentially Torrent type piracy.
If I'm right, please remove their account a.s.a.p.
