I recently came across quite the interesting playlist maker to help discover all kind of new music. It goes by the name of Boil The Frog and works (presumably) through Spotify algorithms.
The concept behind it quite simple and the results are generally golden. You enter two artists, doesn’t matter how similar or different they are, and Boil The Frog creates a playlist from point A to point B. Basically, it creates a spectrum of music or a bridge from one artist to the other.
