> It did a really good job classifying trance music while at the other end of the scale was hip hop / R&B with 61%, which is still almost 6 times better than randomly assigning a genre to the image. I suspect that there’s some crossover between hip hop, breakbeat and dancehall and that might have resulted in a lower classification accuracy.

The first step to analyze this is to make a confusion matrix, [1]. It would be nice if the article included it.
