I know I'm not part of your crew, but I just want to brag a bit.

1. I've memorized a ballad song from a male KPOP group from the '90's called Solid, titled "Hold On To The End Of Tonight."
They were known as "Korean Boyz II Men."
So, if I were to somewhat compare it to a Boyz II Men song, it would be their "End Of The Road."
2. I've memorized an old Girls' Generation's ballad song called "Mistake" from their 3rd mini-album.
I loved it even more after knowing Yuri composed the lyrics.
So, do I sing them well? I don't know. I'm not a trained singer, but, as a very low amateur, I've tried to hit the right notes in my ears.
Edit ~ I'm done so I'll leave now.
