While it's a great technology, the result sounds somewhat robotic. On the original recording the voice sounds soft, but after separation it sounds like it is synthesized or passed through a vocoder, something is missing. The voice contains pieces of strumming sound. Guitar also sounds "blurred", as if someone cut an object from the picture and blurred the cut to make it less visible. Clap sound is distorted, on the original recording it sounds the same, but after separation it sounds different every time, as if it was filtered or compressed with low bitrate.
It is amazing how the ear manages to distinguish all the sounds without distortion.
