Music has always been judged by the listeners own personal taste ad can regularly create seperate social groups in the younger generations. An example of this would be the people that are interested in rock music sterio typically dress all in back and have alot of peicerings. People would categorise this group as Goths and would generally say that they worship the devil and hate life. Not always true but it happens, thats what sterio types give you.
Music always seems to have its own certain time and place and particular type of listener. This regularly allows the listener to be comfortable and relaxed in a ertain atmosphere and should always have a particular context in which they should be consumed.
The medium is the message in the case of music. Music has now become part of our everyday lives and is no longer a ornament to it.
digital advances in music habe done more than change music but changes in culture surrounding it too. some key elelemts of music have only really changed because of technology.
Sometimes now music is no longer composed or written for a particular mood but for a particular place i.e. a airport.
Samplng - any sound can be used. any part f the human everyday life can be made in to a sample. making music to be something else with "samples" of other things does have to be approached in particular ways. a digitally encoded musical body creating something that it totally different. You can take parts of one song and put with parts of another to create a totally new product.
