From what I told, If you want Hasbro to do something about the lack of song dubbing, they have a website where you can fill in a form to contact them. You can also try emailing hasbro_new@mailmw.custhelp.com.
Yeah, I checked, this is the first episode with that option (on YouTube, obviously the Netflix uploads of the first 20 episodes had this from the beginning)
At least when it goes onto Netflix, it will have subtitles automatically appear for the correct language (as long as the English closed captions aren’t selected, if it works how it works for The Sneeze Song and Rule 4 That)
