Uhm, I don't see how it's "unanimously decided" based on two users posting in the thread. There are many other editors here who might have an opinion on this.
I think the lyrics information is incredibly useful and they should remain on the page, thus I would oppose that information being removed, given that such information is almost certainly not going to be found elsewhere. In addition, it's doing no real harm to the wiki as a whole: if it was an issue, I'm surprised it wasn't raised several years ago, instead of when the wiki is largely less active than it was back in the day.
The lyrics info on here helped me significantly in finding the original tracks on YouTube/Spotify and allows me to relate to the song in its English translated version, given the dub does not translate the song vocals at all.
