I've been looking at line distributions for different groups and I noticed that a lot of the times the main or lead vocalists (who have the strongest voices in the groups) don't always get the most lines. SUPER JUNIOR Yesung is considered the main vocalist along with Kyuhyun and Ryewook in Super Junior. But Sorry Sorry he got only 4 seconds less lines than Sungmin, Donghae and Siwon. I like Siwon but is his voice stronger than Yesung? Hell no. Another song Yesung received less lines than Donghae, Siwon, Leeteuk, Eunhyuk, and Sungmin. I'm not putting Ryeowook and Kyu because they are main vocalists also. Again why is one of the main vocalist (Yesung was ranked 2 in SuJu best voices) singing less than sub vocalists? EXO Fans put Chen, Baekhyun, DO and Xiumin in the vocal line. Xiumin is classified as lead vocalist. But his lines are always towards the bottom. He should be fifth in line distribution at worst. The only exception I can think of is BTS in which Jungkook is the main vocalist and gets the most lines and everyone agrees because he has the most stable and versatile voice. But 90% of the time the top vocalists in the group don't necessarily have the most lines. Do you agree with that and why do you think that happens? Is it because the best voice is not very good looking or unpopular? Is it because their voice don't fit the song?
