You don't have to know the songs going in since it is also about showcasing songs too like Sooyoungs Winter Breath doesn't even have 300k views so it can be possible someone finds it through one of the matches it is in and likes it because with some like Gfriends, Oh My Girls and now the SNSD Solo one it can be super obvious who is gonna win but it can still be fun.
Ok, I know almost all SNSD group/solo songs except songs I missed/skipped for some reason like I never knew abt/or it's old/obscure but for other groups except Gfriend/BlackPink-when I've catched/watched their stages/mvs on tv, (music bank/inkigayo/the show/MTV-on cable tv channels:they mostly don't make much impression/memorable so I would hv to listen/watch a few times to vote/rank even two songs in a tournament-if a song don't catch my ear after one listen; it's on to the next song so I can't vote/rank if both songs don't catch my ear.
I'll stick to the tournament where I've listened n remember/hv an impression-after I joined KS, I voted in BP tournament soon after cos I listened to all their songs after their comeback.
I don't think I shd vote if most of the songs r only I think it's nice/ok but I can't rank/vote one higher than the other.
But I think ur doing hard work on the tournaments n don't let this flop (me), not voting keep u from doing wat u r doing to promote the groups/songs to other KS users who r more knowledgeable than me.
Just wanted to share my appreciation for ur efforts.
