Has anyone ever listened to music as well seen colors?

Yes, this phenomenon is called chromesthesia, also known as sound-to-color synesthesia. Synesthesia is a rare condition in which a person experiences a consistent and involuntary sensory experience in response to a non-sensory stimulus. In the case of chromesthesia, individuals perceive colors when they hear music or other auditory stimuli. Each person with chromesthesia experiences their colors uniquely, so there is no singular pattern or association.

Different sounds, instruments, and musical notes may evoke different colors, and the colors might change with the pitch, tempo, or intensity of the music. For some individuals, the colors appear as a visual overlay, while others may perceive the colors internally. It's important to note that chromesthesia is not a hallucination, but rather a neurological condition that affects the way the brain processes sensory information.
