Music player - What does music look like

i use music apps very often, and they all placed the album cover on the playing screen.

But there is some problem: A: some music doesn't have a cover B: songs in the same album have the same album cover C: some cover has no relation to the music

Maybe there is another way to assign a image to a piece of music, and the image will show the style, the rhythm, the emotion, the longth and some other infomation of the music. So when you see a image, you generally know what this music is like.

With this idea, i had a try, and this is my version. I use hue ,contrast, lightness and density to imply those information, can you gusse what is what?
