The idea of my design is that it can be used with anyone’s playlist. Here I have a second playlist; my fathers, he doesn’t have as many songs so there is only one ring instead of 3.
I also tried using a fade effect, the faded moods and songs are the less popular/less played ones. This is an alternative to the rating system. It shows that he listens to more songs in the warmer spectrum (major key with a faster beat) than in the cooler section.
