Glenn McDonald developed an algorithm to generate a word cloud of musical genres:
I started making pictures of the music-genre space for diagnostic purposes at work. The exercise keeps threatening to take on a life of its own, but then each new thing turns out to have some functional purpose after all. Which leads to some other analytical feature, which leads to yet another interesting by-product.
This latest not-so-analytical version here adds a whole new level, literally. If you hover over, or click, any genre in the main map, you’ll see a » link. Click that to see an artist-level map of that genre, complete with representative audio for each artist and a genre-specific car-radio scanner.
