> A neural network learns a representation from the data. It literally scans ur work.

The neural network best know for this ability is the human brain. Aspiring artists and musicians scan many works during training which alter the parameters(synapses) of the neural net, allowing it to better recreate the training data or extrapolate from that data to create new and unique output. Sometimes, the parameters in the neural net are configured so precisely that it becomes possible for it to re-create copyrighted works with high precision. The ability to do this does not constitute copyright infringement. Copyright infringement only occurs if the recreation isn't properly attributed.
