Honestly, I feel like these copyright comparisons are kinda unfair in some cases because there are idols who write the lyrics for the entire song or almost the entire song, while others write like one verse and that makes no difference in these comparisons because both get the copyright for the song, which is just bullshit in my opinion.

This articles and charts are useless. For example some artists like G-Dragon & Zico knowing for writing majority of their songs, and majority of time they wrote them alone! While other artists like RM and Il-hoon, I can't find a single song they wrote alone (if there was probably one or two) , and majority of time they have other 5-10 writers writing with them one song... How can you compare an artist writing his entire song with another one who have 10 writers with him? Stupid.
