It would also be great if instead of "music" it could put the name of the song or describe it somehow.
I, a hearing person who likes subtitles just as a preference, shouldn't have to read a subtitle that's obvious nonsense, go back a couple seconds, and listen again in order to figure out what's going on.

Scripted media has absolutely no excuse for not having subtitles or having subtitles that aren't perfectly verbatim. Professional captioning services should be ashamed of the shoddy work that they put out. Captions should be treated as a part of the production, just like filming, editing, audio balancing, etc - and anything that releases with missing or bad captions should be seen as unfinished
