Well, one thing's for sure: the algorithm proves
that "He's So Fine" was written by George Harrison.
And that the Who wrote some of the Beach Boys' hits - just listen to those vocal arrangements on the early Who albums.
This whole concept of finding "musical fingerprints" really diminishes the concept of collaboration. You can find bits and pieces of lots of influences in all kinds of music.
So, I dub this an experiment not in AI, but in ASS (Artificial Stupidity Syndrome).
