You have heavy metal hitting hard till no one can hear anything else clear.
That is the kind of music I like to move it to, when I am working through an intense workout grove.
But after that exercise session I need mellow music of a different persuasion, less percussion and more piano solos with a slow flow.
The kind of chords that I can daydream to when I am bored,
the kind that lets me wander peacefully discovering new thoughts safely as I go slipping in and out of the wavelength, of soft melodies while locked doors open to these keys that put me at ease.
