I finally solved a strange problem with date metadata field in yt-dlp. When I download tracks from Soundcloud, it gives me 3 audio codecs: mp3, opus and aac. I don't know why, but mp3 get YYYY date, and opus get YYYYMMDD date. I thought it might be because of mp3 ID3 format.
Anyway, I managed to figure out how to set formatted date:
--parse-metadata "%(upload_date>%Y-%m-%d)s:%(meta_date)s" --add-metadata
