My brother was born deaf. He experiences music through vibrations. He has his favorite bands and songs like anyone else. Closed Captioning in relation to music is largely useless, except as a que for the playing of said music.
Note: I’m not deaf, but my brother is. This is his explanation paraphrased, not mine. Also, I can’t watch anything without Closed Captioning, as it was always on for my brother growing up.
