Okay, with this recent petition I have been thinking more about magic in the context of it being an art like film, music, art then a question came to mind: If I watch a magician do a trick, then figure out how to do the trick, that is frowned upon in the community because I did not pay for the rights to learn and perform it. But if I hear a song on the radio that I like, then go home grab my guitar and figure how to play it, that is called a cover and it is just fine. If we are to consider arts on a level playing field what is the difference here?
