Feature request: ignore transcriptions of music

[kytrinyx]

One of the most annoying features of the crowdsourced subtitles from Viki is that they insist on transcribing and translating every single k-pop song. All of them.

They are kind enough, however, to prefix any subtitle lines that are just kpop with unicode note characters.

So far I've found three that are in use:

♫
♬
♪

Would it be possible to ignore lines that contain these characters in the condensed audio?

Few years late, but this worked for me:
--sub-regex-filter "(.*?♬.*?)|(.*?♪.*?)|(.*?♩.*?)|(.*?♫.*?)"
