I dont think its a controversial opinion if you have common sense.
Dont call a song or anything that your faves have no contribution in as "their masterpiece". Its honestly a shxtty thing to do. Dont ever say its their masterpiece/art(song) when their only contribution is vocals. Praise their vocals, sure. But praising and saying they are the ones who release a "masterpiece"(because of the lyrics, melody, instrument, production) when they have zero contribution is (believe it or not) rude. They literally put credits in every song just for you to praise the wrong people. I thought it would be common sense. Give credits where its due. Not give credit where you want, to make you feel good.
I will give an example:
The group members have no contributions in the lyrics
But then a fan said:
Now, this lyric is a masterpiece, as expected from my faves. They know how to write lyrics to spread a great message.
When in reality they dont have any contribution in the lyrics.
KBYE.
