SPolarfy fetches these nine audio features from the API. If you're interested to learn more about the details, please chenk the documentation. Most of them lie in the range between 0 and 1. Otherwise features get normalized to make them comparable among each other (except for key, which is color coded). The higher the value, the more likely the overall sentiment of the track (or a group of them) aligns with that attribute.
