When it comes to any song (Western, K-Pop, J-Pop, etc) do you prefer the song or its instrumental version?

I don't really like instrumentals

Reasons why I am not liking that ONF is going to drop a full instrumental album or that 6 song-albums these days mean you only get 3 songs

I much prefer songs with vocals.

I see no reason why instrumentals get included sometimes.

I feel like those are simply fillers and the cheapest way to "have full tracks" in the albums.

Maybe someone who knows about music can clarify for the rest of us.

Is it for musicians outside of the industry to learn them??
