I'm not sure if its contradictory to itself.. (that's an oxymoron isn't it?)
I agree with dirty bass about the artists and hacks thing. There are degrees of how high one's emotion is when making music, but usually the best artistic shit comes from, say, someone wanting to cut there ear off..
Yip, the best music comes from the people who love it most and have no agenda but to create it for it's own exsitance and for nothing else.
I think that comes part and parcel.
As for randomisation....good for ideas and learning, bad for final expression of the artist i think, as its not what they wanted to convey it's what a computer did and it takes no effort to think about. Less organic - which is the beauty thats lost!
But to be honest if one is bringing it all together in a masterpiece of music then i don't give a ****.
