With the progression of this technology Music is now irrelevant. In one fell swoop a machine will generate all music that every did, and ever could possibly exist.
All music now exists here and now
Music will no longer be a valuable commodity. Its like diamonds. The only reason music will have valuable is because of a controlled market.
Here is what will happen:
People dont buy music alone. Music made by a nameless, faceless machine will never sell. People buy a face, and an image with the music. The face, the look, and the social image are what most people are really buying, and mostly all they are interested in. So... There will still be fabulously rich "artists" but they are nothing more than glorified fashion models for a computer generated track. The music will be created by a machine from start to finish, and "Britney Spears" cloned "Artists" will parade around the stage passing the music off as their own. and everyone will lover her because her music is so great, and she is so beautiful, and she is sort of a bad ass kinky freaky chic, and she flashes her tit on TV.. and blah blah blah blah
The process is already being done today, but by real people behind the scenes writing the music, mixing the beats, and creating the image for her/him. Now everything will be done by the machine, instantly, on demand, and all they need is a pretty boy or girl to go dance around and act stupid.
In fact they could have an artist perform a brand new "original" track every single time they do a concert... they could in the middle of the show have the computer spit out a completely new song right there on demand based on how the audience is reacting to the one she is currently dancing and singing along too.
Music no longer has any meaning or value. Its just sound noise
