I been thinking about this for a while now... Lets say johnny gets onto big brother, and he brings his guitar in with him. Now every one is aware that big brother is constantly watching, and that everyone in the house can be seen and (more importantly) heard 24/7. Now say johnny grabs his guitar and plays a few notes, and makes up a riff. He constantly plays it, and it ends up being broadcast on national TV. Everyone hears his riff. Yay woo, everyone knows johnny can play guitar. But what about if he plays a Metallica riff, or a Nirvana solo? If the footage of johnny playing this riff or solo goes onto national TV, it is like a public broadcast, johnny is playing someone else material, without the composers consent. have i just lost the plot, or is there a discalimer that is at the end of every show? Thoughts?
