I'm a hearing individual but I'd like to say that I always enjoy subtitles and I really the way they sometimes describe the emotion music intends to convey.
Like when it says "romantic melody" or "suspenseful music." I like having that spelled out for me because sometimes I'll hear the music and I'll get a completely different vibe from what's playing than what was intended.
"Why is this horror scene playing elevator music" has been a real question I've asked myself, only for the subtitles to tell me I misinterpreted the music.
