English subtitles would be awesome but Netflix for some reason want to force users to use closed captions. There's always a long list of subtitle languages and then one in English with closed captions.
CC subtitle tracks often show up with the name "English (SDH)" (Subtitles for the Deaf and Hard of hearing).
When the CC is good it can communicate the mood of the music that is playing, sometimes it even shows the lyrics.
